plat-nomadik: make GPIO interrupts work with cpuidle ApSleep

Enable wakeups by default for any GPIO interrupts and in the suspend/resume
path narrow this down to only the the real wakeup interrupts. This approach is
based on the assumption that cpuidle ApSleep will be entered more often than
system suspend.

mach-ux500: basic HREFv60 support v2

readily available internal GPIO pins instead.

This will centralize all GPIO pin muxing for the different boards

plat-nomadik: fix compilation warning

The compiler warns that [rf]wimsc may be used uninitialized in

plat-nomadik: get rid of unused GPIO PM code

The NOMADIK_GPIO_PM config option is disabled by default, not user visible,

GPIO registers need not be saved and restored since their values are
preserved when vAPE (on DB8500) is powered down.

plat-nomadik: implement safe switch sequence for Alt-C

Setting pinmux alternative C for a GPIO pin is actually not
so easy since it ivolves setting value "1" in two registers,
and since the combined result will take effect for intermediate
values (01 or 10) this will cause glitches while you wrote one
register but have not yet written the other.

This patch implements a series of kludges including an optional
machine-specific callback to avoid glitches when changing pin
mux mode to alternative C.

When GPIOs wake up the system from sleep mode, the normal GPIO interrupt

the suspend/resume code.

mmc: sdio: Allow sdio operations in other threads during sdio_add_func()

This fixes a bug introduced by 807e8e40673d ("mmc: Fix sd/sdio/mmc
initialization frequency retries") that prevented SDIO drivers from
performing SDIO commands in their probe routines -- the above patch
called mmc_claim_host() before sdio_add_func(), which causes a deadlock
if an external SDIO driver calls sdio_claim_host().

Fix tested on an OLPC XO-1.75 with libertas on SDIO.

drm/nv50-nvc0: prevent multiple vm/bar flushes occuring simultanenously

The per-vm mutex doesn't prevent this completely, a flush coming from the
BAR VM could potentially happen at the same time as one for the channel
VM. Not to mention that if/when we get per-client/channel VM, this will
happen far more frequently.

drm/nouveau: fix regression causing ttm to not be able to evict vram

TTM assumes an error condition from man->func->get_node() means that
something went horribly wrong, and causes it to bail.

The driver is supposed to return 0, and leave mm_node == NULL to
signal that it couldn't allocate any memory.

changes since v2:

- use v3 and v4 for specifying the ip version instead of i.MX23/28.
This is a better namespace when future versions are added.
- rename mach/fb.h to mach/mxsfb.h

changes since v1:
- Add a LCDC_ prefix to the register names.
- use set/clear registers where appropriate
- protect call to mxsfb_disable_controller() in mxsfb_remove()
