soc/mediatek/mt8192: add rtc MT6359P driver
Add rtc MT6359P driver for rtc init and rtc eosc calibration. Refactor
mt8173 and mt8183 code by extracting common API. Move rtc_read and
rtc_write to each SoC folder, because mt8173 and mt8183 access rtc via
pmic wrapper, while mt8192 accesses it via pmif.
