On thermal device interrupt, if the interrupt is generated for passing
power floor status, call the callback to pass notification to the user
space.

First call proc_thermal_check_power_floor_intr() to check interrupt, if
this callback returns true, wake the IRQ thread to call
proc_thermal_power_floor_intr_callback() to notify user space.
