rtc: pm8xxx: drop bogus locking

Since commit c8d523a4b053 ("drivers/rtc/rtc-pm8xxx.c: rework to support
pm8941 rtc") which removed the shadow control register there is no need
for a driver lock.

Specifically, the rtc ops are serialised by rtc core and the interrupt
handler only unconditionally disables the alarm using the alarm_ctrl
register.

Note that since only the alarm enable bit of alarm_ctrl is used after
enabling the RTC at probe, the locking was not needed when doing open
coded read-modify-write cycles either.
