i2c: npcm7xx: Group bank 0/1 registers together for readability

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.
