rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed
[ Upstream commit 34719de919af07682861cb0fa2bcf64da33ecf44 ] 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.
