The unlabelled registers NPCM_I2CCTL4 to NPCM_I2CSCLHT overlap with the
bank 1 registers below, and they are accessed after selecting bank 0, so
they clearly belong to bank 0.

Move them together with the other bank 0 registers, and move the
unrelated definition of npcm_i2caddr down to keep the banked registers
in one piece.

To make the code easier to understand, add longer names to the
definitions of register fields. These longer names are based on source
code published by DELL/AESS for WPCM450, but should apply just as well
to NPCM7xx and NPCM8xx.
