When the remote processor wants to wake up local processor
it toggles one of the GPIO. The IRQ handler at local
end will notify registered listeners about it.

The user watchdog was waiting the hardware watchdog bite by
stop petting it. But in the cpu suspend scenarios, the auto petting
by hardware prevent the expected watchdog bite. So add a new user pet
timer to explicitly trigger the watchdog bite by software when the user
watchdog petting is not happenned before timeout.

Currently both Blair and Holi use the same MPM pins mapping
configuration as they use the same compatible string. USB PHY
has a different GIC IRQ on Blair, so different MPM configuration
is required.

Add SMP2P handshakes according to below sequence to manage

1. Host driver calls prevent_l1.
2. ICNSS sends SMP2P to FW with PCI_EP_POWER_SAVE_EXIT.
3. FW bring EP out of power save and update in memory

4. Once Host reads updated value it access registers.
4. Host driver calls allow_l1.
5. ICNSS send SMP2P to FW with PCI_EP_POWER_SAVE_ENTER.

The existing boot_stats module captures the timestamps
of various events before the kernel start, like bootloader
start, kernel load time, etc.
Extend support to capture timestamps of events after kernel
starts execution. Users can call place_marker from different
points of execution to capture the timestamp.
Expose a sysfs node to read the complete list of events
captured by the boot_stats module.

As cpus can serve ipis and timers during suspend and
resume; msm watchdog would periodically pet hardware,
even when some of suspend/resume callbacks are stuck,
due to software deadlocks. This can cause device hangs,
particularly when noirq callbacks are stuck. To recover
from this, register late suspend (and early resume)
callbacks in msm watchdog; these callbacks would
disable/enable watchdog pet.
