As the last pxa related driver was converted to dmaengine, it's time to
kill the legacy dma code, which is not used anymore.
This finishes the pxa dmaengine transition.

With all dependencies taken care of, this enables building
the Marvell mmp platform as part of ARCH_MULTIPLATFORM, along
with other ARMv5 and ARMv7 platforms.

PXA95x isn't widely used. And it adds the effort on supporting
multiple platform. So remove it.
The assumption is that nobody will miss this support. If you are
reading this text because you actually require pxa95x support on
a new kernel, we can work out a way to revert this patch or add
support to the mmp platform.

This commit moves the PXA PWM driver to the drivers/pwm subdirectory and
converts it to use the new PWM framework.

As per example from the other ARM boards, push the PXA
GPIO driver down to the GPIO subsystem so it can be consolidated.

The core of PXA955 is PJ4. Add new PJ4 support. And add new macro
CONFIG_PXA95x.

Not tested and enabled on MMP at this moment, and since the IRQ
is different from mach-pxa, I'd prefer to move the PMU device
back into mach-pxa/. Will introduce the PMU device to MMP once
it's enabled and tested.

PMU is not tested and enabled on MMP architecture at this moment,
the device IRQ number, IRQ_PMU depends on ARCH_PXA. Build PMU only
for ARCH_PXA.

This patch adds an initcall for the pxa platforms so that they
register their PMU IRQs with the PMU framework in the Kernel.

arch/arm/plat-pxa/mfp.c is not intended to be use by PXA25x/PXA27x,
make it explicit here only for use by PXA3xx or ARCH_MMP.

1. add common GPIO handling code into [arch/arm/plat-pxa]
2. common code in <mach/gpio.h> moved into <plat/gpio.h>, new processors
should implement its own <mach/gpio.h>, provide the following required
definitions and '#include <plat/gpio.h>' in the end:
- GPIO_REGS_VIRT for mapped virtual address of the GPIO registers'
physical I/O memory
- macros of GPLR(), GPSR(), GPDR() for constant optimization for
functions gpio_{set,get}_value() (so that bit-bang code can still
have tolerable performance)
- NR_BUILTIN_GPIO for the number of onchip GPIO
- definitions of __gpio_is_inverted() and __gpio_is_occupied(), they
can be either macros or inlined functions

1. introduce folder of 'arch/arm/plat-pxa' for common code across different
PXA processor families
2. initially moved DMA code into plat-pxa
3. common code in <mach/dma.h> moved into <plat/dma.h>, new processors
should implement its own <mach/dma.h>, provide the following required
definitions and '#include <plat/dma.h>' in the end:
- DMAC_REGS_VIRT for mapped virtual address of the DMA registers'
physical I/O memory
