  ARM: pxa: use common IOMEM definition
  ARM: dma-mapping: convert ARCH_HAS_DMA_SET_COHERENT_MASK to kconfig symbol

Commit 6f6f6a70 "ARM: create a common IOMEM definition" moved macro
IOMEM(), and requires users to include <asm/assembler.h>. Fix Tegra's
sleep.S to do so. This fixes:

arch/arm/mach-tegra/sleep.S: Assembler messages:
arch/arm/mach-tegra/sleep.S:77: Error: missing ')'
arch/arm/mach-tegra/sleep.S:77: Error: garbage following instruction
    -- `movw r0,#:lower16:(0x60007000-0x60000000+IOMEM(0xFE200000))'

Note: This only shows up after 0a258935 "ARM: tegra: update defconfig"

pxa was missed in the moving of IOMEM to a common definition, so lots of
IOMEM redefined warnings were introduced. So remove pxa IOMEM definition
and fix all the fallout.

The only users of ARCH_HAS_DMA_SET_COHERENT_MASK are 2 ARM platforms:
ixp4xx and pxa cm_x2xx. We've been getting lucky that the define is
implicitly included before dma-mapping.h, but the removal of io.h broke
things (c334bc15 ARM: make mach/io.h include optional). Since memory.h
is the correct place, but no longer exists, convert the define to a
kconfig entry.

In previous patch (arm/tegra: add timeout to PCIe PLL lock detection loop)
tegra_pcie_enable_controller() function type has been changed from
void to int, but the last return statement wasn't converted, so
function returns undefined value. Fix it.

Also while at it, address couple of minor concerns raised by reviewers:
use usleep_range for delay, and lower the value of timeout to 300ms
to be consistent with Nvidia Vibrante kernel.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Commit 1dfe34ae (ARM: iop13xx: use runtime ioremap hook) missed

With commit 4fe7ef3a (ARM: provide runtime hook for ioremap/iounmap),
compiles with !CONFIG_MMU were broken. Rename nommu __iounmap to
__arm_iounmap and add arch_ioremap_caller and arch_iounmap. Its
not expected that these need to be overriden for !CONFIG_MMU, so setting
the function ptrs has no effect in this case.

Tegra PCIe driver waits for PLL to lock using busy loop.
If PLL fails to lock for some reason, this leads to silent lockup
while booting (as PCIe code is not modular).

Fix by adding timeout, so if PLL doesn't lock in a couple
of seconds, just PCIe driver fails and machine continues to boot.

Add a kconfig option NEED_MACH_IO_H to conditionally include mach/io.h.

Basing this on CONFIG_PCI and CONFIG_ISA doesn't quite work. Most ISA
platforms don't need mach/io.h, but ebsa110 does. Most PCI platforms need
mach/io.h for now, but ks8695 doesn't which means i/o accesses are broken.
