ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+
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.

serial: omap: fix DeviceTree boot
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
e5b57c0 (serial: omap: define helpers
for pdata function pointers) failed to take DT
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
pointer.

struct omap_board_config_kernel defined in the board files

Remove the struct omap_board_config_kernel instances from the board

Also remove the omap_get_nr_config() macro and the omap_get_var_config()
