- Add support for LFA device node in the kernel driver. Implement
probe() to register LFA interrupt and threaded interrupt service
function.
- CPUs will be rendezvoused during activation.
- On IRQ, driver will query FW components then triggers activation of
capable and pending components.
- Mutex synchronization is implemented to avoid concurrent LFA updates
through interrupt and sysfs interfaces.
- Refactor LFA CANCEL logic into independent lfa_cancel() function.
- Enhance PRIME/ACTIVATION functions to touch watchdog and implement
timeouts.

I was expecting to the devicetree binding based on $subject but no.
So this patch can't be reviewed without one.
