device_register is marked __must_check, so we better propagate the error
value by returning it from ecard_probe.
Without this patch, building rpc_defconfig results in:
arch/arm/mach-rpc/ecard.c: In function 'ecard_probe':
arch/arm/mach-rpc/ecard.c:963:17: warning: ignoring return value of 'device_register', declared with attribute warn_unused_result [-Wunused-result]

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."
Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

Get rid of the NO_IRQ madness from Acorn expansion card handling code.
Thankfully, are relatively few users of this here, and so it's easy to
audit.

This register is only present on older platforms, and not on RiscPC,
so lets remove this unused support.

Use irq chip data to store the expansion card data pointer, rather
than converting from the interrupt number to a slot number. This
allows the interrupt chip methods to avoid knowing about interrupt
numbering.

RiscPC is the only platform using the Acorn expansion card support, so
move it into its mach-* directory.
