CVS commit: src/sys/arch/x86/pci

Module Name:	src
Committed By:	andvar

Modified Files:
	src/sys/arch/x86/pci: rdcpcib.c

Log Message:
rdcpcib(4): fix rdcpcib attach/detach handling for function 0 and function 1.

Only function 0 exposes the indirect access registers and the watchdog timer.
Function 1 has a separate register set and does not use these registers.

This resolves the autoconfiguration error seen in boot dmesg:
"rdcpcib1: autoconfiguration error: couldn't map indirect registers"

Attach now maps the indirect access registers and configures the watchdog only
for function 0, and detach only releases resources that were initialized.
