rtc: mpfs: remove 'pending' variable from mpfs_rtc_wakeup_irq_handler()
cppcheck reports
[drivers/rtc/rtc-mpfs.c:219]: (style) Variable 'pending' is assigned a value that is never used.
The fetched CONTROL_REG stored in pending is unused and partially
duplicates the functionality of the later call to mpfs_rtc_clear(). This looks
like leftover development code, so remove pending.
