Commit c2dd114d2486 ("ARM: EXYNOS: fix register setup for AFTR mode
code") added S5P_CENTRAL_SEQ_OPTION register setup fix for all
Exynos SoCs to AFTR mode code-path. It turned out that for coupled
cpuidle AFTR mode on Exynos4210 (added by the next patch) applying
this fix causes lockup so enable it in the AFTR mode code-path only
on SoCs that require it (in the suspend code-path it can be always
applied like it was before commit c2dd114d2486 ("ARM: EXYNOS: fix
register setup for AFTR mode code")

knav_range_setup_acc_irq() is used only within the file and should
be defined as static.

Currently configuring qmss and dma as dynamic module creates three .ko
files. knav_qmss_acc.ko and knav_qmss_queue.ko both can't be insmod
because of circular dependency. So combine these two into one module
by changing the makefile.

Until the driver is corrected to stop including mach/at91_ramc.h and using
mach/io.h, it won't compile in a ARCH_MULTIPLATFORM configuration.

Currently only few of the API calls are exported. This creates problem
when the knav* modules are built as modules and another user module
such as netcp_core try to use these API calls and they are also built
as module. This patch export these APIs to address the issue.
This is needed to support allmodconfig for ARM

Now that we can create and attach to IOMMU domains via of_dma_configure,
make sure we give the architecture a chance to tear them down when a
platform or amba device is destroyed.

Three compatible strings have been added to the at91_udc driver.

cpu_is_at91xxx are a set of macros defined in mach/cpu.h and are here used
to detect the SoC we are booting on.
Use compatible string + a caps structure to replace those cpu_is_xxx tests.
Remove all mach and asm headers (which are now unused).

Since non-DT board support has been removed from the at91 architecture we
can safely remove non-DT handling code.

The at91_udc driver request 2 clocks, and thus need them to be defined in
the device tree.
Document the clocks and clock-names properties so that everybody use the
correct names.

The driver is requesting clock by their global name (those declared in the
clk_lookup list), but this only works with !CCF kernels.
Now that all SoCs have moved to CCF, fix the driver to use local names
(hclk and pclk).
