rtc: isl12022: switch to using regmap API
The regmap abstraction allows us to avoid the private i2c transfer helpers, and also offers some nice utility functions such as the regmap_update_bits family. While at it, simplify the code even more by not keeping track of ->write_enabled: rtc_set_time is not a hot path, so one extra i2c read doesn't hurt (regmap_update_bits elides the write when the bits are already as desired).
