Introduces a new build flag 'DYNAMIC_SINGLE_CHIP':
If DYNAMIC_SINGLE_CHIP is defined, which means there
are multiple possible drivers, but only requires one
instance of driver at a time. In such case, leave
MULTI_IF_NAME undefined, no matter what the module
name is, only prepend DYNAMIC_SINGLE_CHIP to names
of firmware/mac/ini files.
Take path of driverdump and ini file for example:
If both MULTI_IF_NAME and DYNAMIC_SINGLE_CHIP are not
defined, the paths are:
driverdump: '/proc/debugdriver/driverdump'
ini: '/<fw_root>/wlan/qca_cld/WCNSS_qcom_cfg.ini'
If DYNAMIC_SINGLE_CHIP is defined as 'qca6174':
driverdump: '/proc/debugdriver/driverdump'
ini: '/<fw_root>/wlan/qca_cld/qca6174/WCNSS_qcom_cfg.ini'
If MULTI_IF_NAME is defined as 'qca6174' and
DYNAMIC_SINGLE_CHIP is not defined:
driverdump: '/proc/debugdriverqca6174/driverdump'
ini: '/<fw_root>/wlan/qca_cld/qca6174/WCNSS_qcom_cfg.ini'
On LA platform, DYNAMIC_SINGLE_CHIP is controlled by
TARGET_WLAN_CHIP and TARGET_MULTI_WLAN:
If more than one WLAN devices are enabled in TARGET_WLAN_CHIP,
and TARGET_MULTI_WLAN is not set to 'true',
DYNAMIC_SINGLE_CHIP will be set to the device name, to
avoid name conflicts of firmware/mac/ini files;
meanwhile, MODNAME is set to 'wlan', then paths for
debugging are not changed.
Otherwise, MULTI_IF_NAME will be defined if requires
multiple instances of driver.

A bus can have multiple sub interfaces or pipes.
USB bus for example has endpoints grouped into interfaces.
WLAN uses one of these interfaces.
Each interface has its own "struct device". Add support to save

Also pass interface dev to pld_usb_wlan_enable() as CNSS expects
interface device.

Currently MAC addresses are generated by driver only.
MAC addresses are queried from platform driver or wlan_mac.bin.
If platform driver gives mac addresses, driver uses it, else it
will use wlan_mac.bin to update MAC addresses. If wlan_mac.bin also
don't have MAC addresses then random MAC addresses are generated
using the HW address or using device serial number.
Add an ini support to enable MAC provisioning. If MAC provisioning
is enabled, ensure that platform driver provides atleast 2 provisioned
MAC addresses. Query the derived addresses also from platform driver.
Generate the remaining random MAC addresses.

The platform driver uevent handling in WLAN handles both the firmware-
down and "recovery" events. However, the recovery event on snoc
platforms is actually the firmware-crashed event. Recovery _is_ a valid
uevent for pcie platforms, but I20db3698602ea273038a3f024b4e5f61639f6d74
is adding support for the firmware down event.
Additionally, there is no good reason to handle both events, and the
various handling logics are spread across both events with little rhyme
or reason. Remove handling of the "recovery" platform uevent, and move all
associated logic to the firmware-down uevent handling.

Currently, driver don't fully support MULTI_IF_NAME when two wlan
cards are supported by using two drivers:
1. if two wlan cards are all PCIe, driver can't distinguish
two PCIe cards firmware path.
2. When create hdd sysfs file upper folder, it will repeatly create the
same folder if not use MULTI_IF_NAME to distinguish them. It's not
necessary to distinguish the sub-folder once upper folder is different.

If modem crashed during wlan driver unloading, icnss driver
will call driver uevent callback to set FW down status in
driver side when it receives BEFORE_SHUTDOWN notification.
If wlan driver is de-initialized just before the callback
is called, kernel will panic as driver's context is freed.
This can be avoid by not setting FW status in host driver.
Instead, icnss driver provides an API to host driver to
check FW status and host driver calls this API before any timeout
assert or accessing HW registers.
