mb/pcengines/apu2/BiosCallOuts: don't have binaryPI clear LPC decodes
Tell binaryPI to not disable the LPC decodes for the IO ports used by
the serial ports on the Super I/O chip during the AmdInitReset binaryPI
entry point. Checked the Stoneyridge binaryPI source code which is
closely enough related to be reasonable sure that this option only
controls which LPC decode bits get cleared and won't have any other side
effects.
TEST=Now the full console output from the APU2 board gets printed on the
serial console.
