xirc2ps_cs: fix register access when enabling FullDuplex
The current code incorrectly passes (XIRCREG1_ECR | FullDuplex) as
the register address to GetByte(), instead of fetching the register
value and OR-ing it with FullDuplex. This results in an invalid
register access.
Fix it by reading XIRCREG1_ECR first, then or-ing with FullDuplex
before writing it back.
