i2c: npcm: Correct register access width
The SMBnCTL3 register is 8-bit wide and the 32-bit access was always
incorrect, but simply didn't cause a visible error on the 32-bit machine.
On the 64-bit machine, the kernel message reports that ESR value is
0x96000021. Checking Arm Architecture Reference Manual Armv8 suggests that
it's the alignment fault.
SMBnCTL3's address is 0xE.
