pbl: generalize fsl i2c_early API into pbl_i2c
The prebootloader is inherently board-specific, so it's natural to
hardcode the i2c driver used and we only support fsl_i2c at the moment
anyway. For abstractions used by different prebootloaders though
(e.g. PMIC writing, SPD EEPROM decoding), it would be good for generic
code to use a pbl_i2c abstraction, so it can be reused across PBLs using
different I2C controllers. Add such an abstraction and use it where
appropriate.
