CONFIG_OF_IRQ is not available on some platforms and using of_irq_*
breaks the build. Since resources are already populated in the platform
device, get the irq from there instead.

Add basic support for pata on iMX. It has been tested only on imx51.
SDMA support will probably be added later so this version supports only
PIO.
v2:
- enable only when needed IORDY
- use dev_get_drvdata
v3:
- add missing clk_put() calls
- use platform_get_irq()
- fix resume code to avoid disabling IORDY on resume
v4:
- Remove EXPERIMENTAL and switch to depends on ARCH_MXC
- Use devm_kzalloc()
- make clock a must-have
- Use only 1 ioremap

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

CONFIG_HAVE_PATA_PLATFORM, by virtue of where its defined, has a
dependency on CONFG_ATA and CONFIG_ATA_SFF. This causes Kconfig
warnings when it is selected by various architectures, such as
warning: (ARCH_VEXPRESS && <choice> || ARCH_RPC && <choice> || MACH_VPAC270 && ARCH_PXA || MACH_REALVIEW_PB11MP && ARCH_REALVIEW || MACH_REALVIEW_PBA8 && ARCH_REALVIEW || MACH_REALVIEW_PBX && ARCH_REALVIEW || MACH_BAST_IDE && ARCH_S3C2410 || MACH_ANUBIS && ARCH_S3C2410) selects HAVE_PATA_PLATFORM which has unmet direct dependencies (ATA && ATA_SFF)
Since this option is only used to control visibility of the
CONFIG_PATA_PLATFORM option and isn't itself visible in the menu,
it is straightforward to simply remove these dependencies rather
than adjust all the architectures.

pata_cs5536 does work on the other platforms(e.g. Loongson, a MIPS
variant), so, remove the dependency of X86_32 and fix the building
errors under the other platforms via only reserving the X86_32 specific
parts for X86_32.
pata_amd also supports cs5536 IDE controller, but this one saves about
33k for the compressed kernel image(vmlinuz for MIPS).

Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA.
In Kconfig, drivers are grouped into five groups - non-SFF native, SFF
w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic
fallback / legacy ones. Kconfig and Makefile are reorganized
according to the groups and ordered alphabetically inside each group.
ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into
CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and
functions.
This increase the binary size slightly when BMDMA is enabled but on
both native-only and PIO-only configurations the size is slightly
reduced. Either way, the size difference is insignificant. This
change is more meaningful to signify the separation between SFF and
BMDMA and as a tool to verify the separation.
