PM: sleep: wakeirq: drop unused enable helpers 

Drop the wake-irq enable and disable helpers which have not been used
since commit bed570307e ("PM / wakeirq: Fix dedicated wakeirq for
drivers not using autosuspend").

Note that these functions are essentially just leftovers from the first
iteration of the wake-irq implementation where device drivers were
supposed to call these functions themselves instead of PM core (as
is also indicated by the bogus kernel doc comments).
