sthal: 9.5.1 porting
Handle user space crashes
+ Impllemented two new IOCTLs to get the FW state and to do FW reset
+ In case the user space service crashes then the ST HAL will get
restarted and all the apps will try to restart their usecases.
Query for the firmware status,
* IAXXX_FW_IDLE - Nothing is running on the chip,
firmware is in idle state, no need to do anything.
* IAXXX_FW_CRASH - Firmware has crashed, set ST HAL to not ready
and wait for recovery to complete
* IAXXX_FW_ACTIVE - Some usecase is running in the firmware,
so request the driver to redownload the firmware and set ST HAL to not
ready state and wait until firmware download is completed
Bug: 129505523
Test: build pass
