Pull ARM fixes from Russell King: "Nothing too disasterous, the biggest thing being the removal of the regulator support for vcore in the AMBA driver; only one SoC was using this and it got broken during the last merge window, which then started causing problems for other people.

Commit 26f41062f28d ("PCI: check for pci bar restore completion and
retry") attempted to address problems with PCI BAR restoration on
systems where FLR had not been completed before pci_restore_state() was
called, but it did that in an utterly wrong way.
First off, instead of retrying the writes for the BAR registers only, it
did that for all of the PCI config space of the device, including the
status register (whose value after the write quite obviously need not be
the same as the written one). Second, it added arbitrary delay to
pci_restore_state() even for systems where the PCI config space
restoration was successful at first attempt. Finally, the mdelay(10) it
added to every iteration of the writing loop was way too much of a delay
for any reasonable device.
All of this actually caused resume failures for some devices on Mikko's
system.
To fix the regression, make pci_restore_state() only retry the writes
for BAR registers and only wait if the first read from the register
doesn't return the written value. Additionaly, make it wait for 1 ms,
instead of 10 ms, after every failing attempt to write into config
space.

Commit 18a4d0a22ed6 ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.
Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.

The OMAP driver needs a 'depends on ARCH_OMAP2PLUS' since it only builds for OMAP2+ platforms. This 'depends on' was in the original patch from Russell King, but was erroneously removed by me when making this option user-selectable in commit b09db45c (cpufreq: OMAP driver depends CPUfreq tables.) This patch remedies that. Apologies to Russell King for breaking his originally working patch. Also, thanks to Grazvydas Ignotas for reporting the same problem.
