Enable pinctrl dummy states for all OMAP platforms that don't
populate DT. This allows drivers to be converted to pinctrl
and not generate new warnings on platforms that do not provide
pinctrl data. These platforms already have pinmuxes configured
before the drivers probe.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke
compile for non-omap as include plat/cpu.h was added. This header
was indirectly included earlier when SPARSE_IRQ was not set, but
does not exist on most platforms.

Fix the problem by removing the cpu_is_omap usage that should
not exist in drivers at all. We can do this by adding proper
clock aliases for the twl-core.c drivers, and drop separate
handling for cases when clock framework is not available as
the behaviour will stay the same.

Note that we need to add a platform device to avoid using the
i2c provided names that may be different on various omaps.

There's no need to have these in plat-omap any longer. Note that these
could eventually be made local to mach-omap1 instead of being in mach.

But to do that, at least various driver access using omap7xxx.h registers
needs to be fixed first.

As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.

Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.

The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.

Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.

Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.

Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.

While at it, also sort some of the includes in the standard way.

Remove hardcoded IRQs in irqs.h and related files as these

As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.

Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.

While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.

Note that for drivers/staging/tidspbridge we just define things
locally.

Changes for GPMC (General Purpose Memory Controller) that take it
closer for being just a regular device driver.

Remove the ancient omap specific atags that are no longer needed.

At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.

There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.

These workarounds do not apply for CONFIG_ARCH_OMAP2PLUS at all,
so let's make it just CONFIG_ARCH_OMAP1.

On some machines using a specific hardware for console screen output,
the update of the pixel frame buffer does not work correctly when
using command line edition. This may be due to a memory cache bug
in the machine on which the problem has been found, but an other
solution is possible.

This patch proposes to avoid touching directly the pixel frame buffer
and to rebuild each character using the standard putc() function
on command line edition.

The resulting code is smaller and not obviously slower (no read
access to the pixel frame buffer).

OMAP Architecture code, passes a few function
pointers for UART driver to use in order to
properly implement Power Management and Wakeup
capabilities.

The problem is that those function pointers,
which are passed (ab)using platform_data on
non-DT kernels, can't be passed down to drivers
through DT.

commit e5b57c03 (serial: omap: define helpers

kernels into consideration and caused a regression
to DT kernel boot.

Fix that by (re-)adding a check for valid pdata
pointer together with valid pdata->$FUNCTION
