rtc: cmos: Call rtc_wake_setup() from cmos_do_probe()

rtc: cmos: Call rtc_wake_setup() from cmos_do_probe()

[ Upstream commit 375bbba09692fe4c5218eddee8e312dd733fa846 ]

To reduce code duplication, move the invocation of rtc_wake_setup()
into cmos_do_probe() and simplify the callers of the latter.

No intentional functional impact.
