i2c: Convert CONFIG_POWER_I2C et al to Kconfig
This converts the following to Kconfig:
CONFIG_POWER_I2C
CONFIG_POWER_LEGACY
They are handled at the same time due to a dependency between them.
Update the Makefile rule to use legacy power only in U-Boot proper.
Unfortunately a separate rule is needed in SPL to be able to build
legacy power. Add SPL related symbols for both, to allow for SPL-only
usage.
