AMD SB800 southbridge update

This patch enables access to the registers of the hardware monitor
logical device in the superio via isa ports 0x295/0x296.
Previously this was not enabled in the SB8xx LPC device.
This is required for initialisation in init_hwm() in
src/superio/winbond/w83627hf/superio.c and also by OS-level
sensor monitoring such as lm-sensors to access temperature,
fan monitoring and control and voltage registers.
asrock/e350m1 and advansus/a785e-i mainboard changes are included herein.
