On BCM6345, the register offsets for the set/get GPIO registers is wrong.
Use the same logic as the one present in arch/mips/bcm63xx/irq.c to
define the correct gpio_out_low_reg value when support for BCM6345
is compiled in.

Though BCM6345 does not technically have the same MPI register layout
than the other SoCs, reading the chip-select registers is done the same
way, and particularly for chip-select 0, which is the boot flash.

Some embedded devices like the Netgear WNDR3300 have two SSB based cards
without an own sprom on the pci bus. We have to provide two different
fallback sproms for these and this was not possible with the old solution.
In the bcm47xx architecture the sprom data is stored in the nvram in the
main flash storage. The architecture code will be able to fill the sprom
with the stored data based on the bus where the device was found.

The bcm63xx code should do the same thing as before, just using the new
API.

BMIPS processor cores are used in 50+ different chipsets spread across
5+ product lines.  In many cases the chipsets do not share the same
peripheral register layouts, the same register blocks, the same
interrupt controllers, the same memory maps, or much of anything else.

But, across radically different SoCs that share nothing more than the
same BMIPS CPU, a few things are still mostly constant:

SMP operations
Access to performance counters
DMA cache coherency quirks
Cache and memory bus configuration

So, it makes sense to treat each BMIPS processor type as a generic
"building block," rather than tying it to a specific SoC.  This makes it
easier to support a large number of BMIPS-based chipsets without
unnecessary duplication of code, and provides the infrastructure needed
to support BMIPS-proprietary features.

Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
really include it.  Note that this can replace #inclusions of <asm/irq.h>.

This is required for the patch to sort out irqflags handling function naming to
compile on MIPS.

The problem is that these files require access to things like setup_irq() -
which isn't available by #including <linux/interrupt.h>
