Subject: [PATCH v4 3/3] rtc: spacemit: default module when MFD_SPACEMIT_P1
 is enabled

The RTC driver defaulted to the same value as MFD_SPACEMIT_P1, which
caused it to be built-in automatically whenever the PMIC support was
set to y.

This is not always desirable, as the RTC function is not required on
all platforms using the SpacemiT P1 PMIC.
