It's not safe to disable controller if overlay(s) is enabled (results in
system hang). So we avoid to disable controller in this case. Userspace
should choose proper governor to avoid freq changing when overlay is in
use, otherwise LCD may blink.

pxafb_overlay_init is not right place to change Z-ordering,

PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
  in memory allocation failure after ~1h of uptime (system does not have
  115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
  allocated.

Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.

This patch attempts to fix those issues.

Patch is based on Russell King's work.

This fixes a bug introduced by 807e8e40 ("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.

Early gen3 and gen2 chipset do not have the relaxed per-surface tiling
constraints of the later chipsets, so we need to check that the GTT
alignment is correct for the new tiling. If it is not, we need to
rebind.

Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09
down to the use of GPU semaphores, and we already know that they appear
broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling
GPU semaphores is simply hiding another bug by the latency and
side-effects of the additional device interaction it introduces...)

However, use of semaphores is a massive performance improvement... Only
as long as the system remains stable. Enable at your peril.
