power: make most tps drivers and the twl4030 driver compatible with DM_I2C

Those driver are not DM drivers per se (not using the PMIC/regulator
framework) and are using the legacy I2C API. Make them compatible with
the DM_I2C API.

This impacts the following drivers:
- palmas (used by am57xx/dra7xx evms)
- tps65218 (used by am43xx evms)
- tps65217 and tps65910 (used by am335x evms and am335x boneblack vboot)
- twl4030 (used by omap3_logicpd)
- tps65217 (used by brppt1)
- twl6030
