Commit 086ada54ab
"FB: sa1100: remove global sa1100fb_.*_power function pointers"
got rid of all instances but one in locomolcd.c -- which was
conditional on CONFIG_SA1100_COLLIE. The associated .power
field which replaces the global is populated in mach-sa1100/collie.c
so move the assignment there, but make it conditional on the
locomolcd support, so use CONFIG_BACKLIGHT_LOCOMO in that file.

Avoid to hard coded irq in rtc-sa1100 driver since we could share
it among arch-sa1100/arch-pxa/arch-mmp.
We still keep hard coded register address since the requirement is
enabling both rtc-sa1100 and rtc-pxa driver. The register addresses
are conflict since they're only two wrappers on the same rtc device.

Since ARM was converted to genirq, the neponset IRQ implementation has
gradually broken as a result of various subtle changes being introduced
into genirq.
It used to be that simple IRQs did not need an IRQ chip. This is no
longer the case, and genirq barfs in irq_set_handler(). Fix this by
introducing a dummy no-op chip, and registering it along with the flow
handler.
Neponset IRQs really don't have any masking ability - all we have is a
status register to allow us to decode the source, and a three input OR
gate inside a CPLD.

GPIO27 is just connected to a CPLD input without any pull-ups or pull-

this pin is driven.

Neponset calls sa1110_mb_disable() from __devinit code, but
sa1110_mb_disable() is marked __init, and so causes a section
mismatch warning.
As sa1110_mb_enable() and sa1110_mb_disable() need to be callable
from suspend/resume paths as well, they must not be marked __init
or __devinit.

Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use
platform resources.) by Jochen Friedrich <jochen@scram.de>, and fixes
applied.
We can safely do this now that we have sanitized host removal; the
original patch had use-after-free bugs in the removal code. Not only
that, but there was no checking of the ioremap() return.
The final change over Jochen's patch is that we wrap the base pointer
selection inside the various register indexes, which reduces the
possibility of the wrong register index being used.
