zhangyi (F) 3df6f61fff PM / sleep: wakeup: Fix build error caused by missing SRCU support 
Commit ea0212f40c (power: auto select CONFIG_SRCU) made the code in
drivers/base/power/wakeup.c use SRCU instead of RCU, but it forgot to
select CONFIG_SRCU in Kconfig, which leads to the following build
error if CONFIG_SRCU is not selected somewhere else:

drivers/built-in.o: In function `wakeup_source_remove':
(.text+0x3c6fc): undefined reference to `synchronize_srcu'
drivers/built-in.o: In function `pm_print_active_wakeup_sources':

drivers/built-in.o: In function `pm_print_active_wakeup_sources':

(.text+0x3d29c): undefined reference to `__srcu_read_unlock'
drivers/built-in.o:(.data+0x4158): undefined reference to `process_srcu'

Fix this error by selecting CONFIG_SRCU when PM_SLEEP is enabled.
