alpha: fixes for specific machine types



Files:

arch/alpha/kernel/core_mcpcia.c
arch/alpha/kernel/sys_rawhide.c
include/asm-alpha/core_mcpcia.h

	Determine correct hose configuration; RAWHIDE family can have
        2 or 4 hoses, so make sure non-existent hoses are ignored.

arch/alpha/kernel/err_titan.c

	Supply a needed #include <asm/irq_regs.h>

arch/alpha/kernel/module.c

	Add some useful output to the relocation overflow messages.

arch/alpha/kernel/sys_noritake.c

	Supply necessary noritake_end_irq() to correct interrupt handling.
	This fixes a problem first noted by hangs during boot probing with
	a DE500-BA TULIP NIC present.

arch/alpha/kernel/sys_sio.c

	Correct saving of original PIRQ register (PCI IRQ routing);
	change default PIRQ setting to leave PCI IRQs 9 and 14 free to
	be used for sound (Multia) and IDE (any), respectively.

include/asm-alpha/io.h

	Supply the "isa_virt_to_bus" routine.
