i2c: omap24xx_i2c: Move away from SoC specific headers for reg offset

Move away from SoC specific headers to handle different register layout.
Instead use driver data to get appropriate register layouts like in the
kernel. While at it, perform some mostly cosmetic alignment/cleanup in
the functions being updated.
