nb/amd/pi/00730F01/state_machine: re-enable LPC decodes

The AmdInitReset entry point of binaryPI disables the LPC decodes for
the serial ports' IO ports causing the serial console output to stop
after this entry point is called until the decodes are re-enabled in
ramstage when the resource enablement is done. This patch re-enables the
LPC IO decoding for the serial ports right after binaryPI disabled it to
get the full log on the serial console.

TEST=Now the full console output from the APU2 board gets printed on the
serial console.
