drivers: base: regmap: introduce REGMAP_I2C
regmap_init_i2c is quite limited right now and only supports 8-bit
registers and values. In future, we may want to expand this further, but
that would require us to format the regmap_config appropriately, pulling
in more code that's not required in the general case, where reg_read and
reg_write can be used directly. Add a new Kconfig symbol and select it
where appropriate to allow us to split formatted regmap handling from
the more basic handling we currently have.
We intentionally don't provide a stub function, so out-of-tree users
without the select fail to link and can be fixed.
