This converts arm to the generic pci_set_dma_mask and
pci_set_consistent_dma_mask (removes HAVE_ARCH_PCI_SET_DMA_MASK for
dmabounce).

As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more
a constant on PXA when multiple processors and platforms are
selected, change TIMER_FREQ in rtc-sa1100.c into a variable.

Since the code to decide the clock tick rate is re-used from
timer.c, introduce a common get_clock_tick_rate() for this.

PXA26x (PXA261/262) is actually a PXA250 with stacked Intel(R)
StartaFlash. And this can be decided by bit 3 (PKG_TYPE) of

Due to this extra I/O register access, make cpu_is_pxa26x() a
public function instead of a macro.

this patch:

  - moves the PXA_LAST_GPIO check into pxa_gpio_mode
  - fixes comment and includes in gpio.h
  - replaces the gpio_set/get_value macros with inline
    functions and adds a non-inline version to avoid
    code explosion when gpio is not a constant.

[ARM] 3044/1: Fix sparse warnings about incompatible pointer types for register defined in pxa-regs.h

Patch from Ian Campbell

The sparse warning initially surfaced in sound/arm/pxa2xx-ac97.c
because it was using u32 * variables to hold the unsigned long *
register addresses.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register
definitions to use u32.

Most other subarches seem to use u32 for their register type, at least
the ones which use a __REG macro (like the PXA) do. Nico indicated in
the thread above that he wouldn't mind this patch.

Changing the type required fixes for opposite warnings in the pxa2xx usb
gadget code but that was the only new warning introduced on defconfig
or lubbock, mainstone and our own PXA255 boards.

Patch from Nicolas Pitre

It used to make a difference in the gcc-2.95 era.  However these days
modern gcc apparently got better at not being influenced by such constructs
(which is good in general) and therefore such workaround is of no real
advantage anymore.
The good news is that gcc (from version 4.1.0) is now fixed with
regards to the defficiency this workaround was trying to address.
For those interested the patch can easily be backported to older gcc
versions and can be found here:

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
