For a legacy ATA controller, libata registers two separate host sets.
There was no connection between the two hosts making it impossible to
traverse all ports related to the controller. This patch adds
host_set->next which points to the second host_set and makes
ata_pci_remove_one() remove all associated host_sets.
* On device removal, all ports hanging off the device are properly
detached. Prior to this patch, ports on the first host_set weren't
detached casuing oops on driver unloading.
* On device removal, both host_sets are properly freed
This will also be used by new power management code to suspend and
resume all ports of a controller. host_set/port representation will
be improved to handle legacy controllers better and this host_set
linking will go away with it.

SIEN on some 3112 controllers doesn't mask SATA IRQ properly. IRQ
stays asserted even after SIEN is masked and IRQ is acked. Also, even
while frozen, any SATA PHY event including hardreset raises SATA IRQ.
Clearing SError seems to be the only way to deassert SATA IRQ.
This patch makes sil_host_intr() clear SError on SATA IRQs and ignore
SATA IRQs reported while frozen so that hardreset doesn't trigger
hotplug event (which ends up hardresetting again).
In such cases, the port still gets re-frozen to minimize the danger of
screaming interrupts. This results in one nil EH repeat on
controllers with broken SIEN but other than that does no harm.

Implement bootplug - boot probing via hotplug path. While loading,
ata_host_add() simply schedules probing and invokes EH. After EH
completes, ata_host_add() scans and assicates them with SCSI devices.
EH path is slightly modified to handle this (e.g. no autopsy during
bootplug). The SCSI part is left in ata_host_add() because it's
shared with legacy path and to keep probing order as before (ATA scan
all ports in host_set then attach all).

Implement ATA part of hotplug. To avoid probing broken devices over
and over again, disabled devices are not automatically detached. They
are detached only if probing is requested for the device or the
associated port is offline. Also, to avoid infinite probing loop,
Each device is probed only once per EH run.
As SATA PHY status is fragile, devices are detached only after it has
used up its recovery chances unless explicitly requested by LLDD or
user (LLDD may request direct detach if, for example, it supports cold
presence detection).

* some controllers can't wait for !BSY after hardreset (LLDD should

* (later) PM needs SRST w/ PMP==15 to operate after hardreset

conditions are met and do a follow-up softreset if necessary.

With hotplug, every reset might be a probing reset and thus something
similar to probe_init() is needed. prereset() method is called before
a series of resets to a port and is the counterpart of postreset().
prereset() can tell EH to use different type of reset or skip reset by
modifying ehc->i.action.
This patch also implements ata_std_prereset(). Most controllers
should be able to use this function directly or with some wrapping.
After hotplug, different controllers need different actions to resume
the PHY and detect the newly attached device. Controllers can be
categorized as follows.
* Controllers which can wait for the first D2H FIS after hotplug.
Note that if the waiting is implemented by polling TF status, there
needs to be a way to set BSY on PHY status change. It can be
implemented by hardware or with the help of the driver.
* Controllers which can wait for the first D2H FIS after sending
COMRESET. These controllers need to issue COMRESET to wait for the
first FIS. Note that the received D2H FIS could be the first D2H
FIS after POR (power-on-reset) or D2H FIS in response to the
COMRESET. Some controllers use COMRESET as TF status
synchronization point and clear TF automatically (sata_sil).
* Controllers which cannot wait for the first D2H FIS reliably.
Blindly issuing SRST to spinning-up device often results in command
issue failure or timeout, causing extended delay. For these
controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT
(currently 8s) to give newly attached device time to spin up, then
issues reset. Note that failing to getting ready in ATA_SPINUP_WAIT
is not critical. libata will retry. So, the timeout needs to be
long enough to spin up most devices.
LLDDs can tell ata_std_prereset() which of above action is needed with
ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags. These flags
are PHY-specific property and will be moved to ata_link later.
While at it, this patch unifies function typedef's such that they all
have named arguments.

With hotplug, PHY always needs to be debounced before a reset as any
reset might find new devices. Extract PHY waiting code from
sata_phy_resume() and extend it to include SStatus debouncing. Note
that sata_phy_debounce() is superset of what used to be done inside
sata_phy_resume().
Three default debounce timing parameters are defined to be used by
hot/boot plug. As resume failure during probing will be properly
handled as errors, timeout doesn't have to be long as before.
probeinit() uses the same timeout to retain the original behavior.
