	src/sys/arch/mips/alchemy/dev: aupsc.c aupscreg.h aupscvar.h

Log Message:
Make PSC better able to support different protocols, as developed for SPI.
The main changes needed are:

	1) pass address and IRQ information from aubus (auspi uses interrupts)

	2) all Au1550 PSC protocols have the same status and register bits
	   for enable, so clean that up (clock registers could be different)

	3) improve timeout logic on enable (a fixed delay isn't good enough)

	4) make aupsc_print return QUIET, as it is annoying to see messages
	   for unconfigured protocols.  This whole mechanism should be re-
	   engineered, to either use indirect configuration or provide more
	   detailed board-driven configuration.  A comment to that effect is
	   placed in the source.

This is shown to work on DBAU1550.
