SBTSI sensors don't work when the CPU is off.
In this case every 'i2c_smbus_read_byte_data' function would fail
by a timeout.
Currently temp1_max/temp1_min file reads can cause two such timeouts
for every read.
Restructure code so there will be no more t
AMD EthanolX CRB uses 2-byte POST codes which are sent to ports 0x80/0x81.
Currently ASPEED controller snoops only 0x80 port and therefore captures
only the lower byte of each POST code.
Enable secondary LPC snooping address to capture the higher byte of POST
codes.

Add GPIO line names for AMD EthanolX customer reference board.
It populates AST2500 GPIO lines (A0-A7 to AC0-AC7) with AMD EthanolX
designated names.

These changes got picked up from my backport patch to the 'dev-5.8'
branch of the OpenBMC Linux repository.
This patch also needed to be added to the main ASPEED Linux kernel, so
it could get into subsequent branches of the OpenBMC Linux repository.

The KCS interface on the LPC channel 3 in the controller
is used for the in-band BMC<->BIOS IPMI communication.
0xCA2 is a default host CPU LPC IO address for this
interface.
