c7f3be4c94 rtc: ds1374: fix RTC_DRV_DS1374_WDT dependencies
It is not enough to select WATCHDOG_CORE, the watchdog part of the driver
now also depends on WATCHDOG. This is currently the best we can do because
alarm support and watchdog support are mutually exclusive.

 "The VL_READ and VL_CLR ioctls have been reworked to be more useful.

34719de919 rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed
Merely enabling I2C and RTC selects REGMAP_I2C and REGMAP_SPI, even when
no driver needs it.  While the former can be moduler, the latter cannot,
and thus becomes built-in.

Fix this by moving the select statements for REGMAP_I2C and REGMAP_SPI
from the RTC_I2C_AND_SPI helper to the individual drivers that depend on
it.

Note that the comment for RTC_I2C_AND_SPI refers to SND_SOC_I2C_AND_SPI
for more information, but the latter does not select REGMAP_{I2C,SPI}
itself, and defers that to the individual drivers, too.
