We only include the template header once, so just inline it into the
source file for the device.

Fix some minor coding style issues in the template header,
so checkpatch doesn't complain when we move the code.

The draw_line16_32() function in the omap_lcdc template header
includes an ifdef for the case where HOST_WORDS_BIGENDIAN matches
TARGET_WORDS_BIGENDIAN. This is trying to optimise for "source
bitmap and destination bitmap format match", but it is broken,
because in this function the formats don't match: the source is
16-bit colour and the destination is 32-bit colour, so a memcpy()
will produce corrupted graphics output. Drop the bogus ifdef.
This bug was introduced in commit ea644cf343129, when we dropped
support for DEPTH values other than 32 from the template header.
The old #if line was
#if DEPTH == 16 && defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN)
and this was mistakenly changed to
#if defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN)
rather than deleting the #if as now having an always-false condition.

The omap_lcdc template header is already only included once, for
DEPTH==32, but it still has all the macro-driven parameterization
for other depths. Expand out all the macros in the header.

surface_bits_per_pixel() always returns 32
so, removing other dead code which is
based on DEPTH !== 32

Behaviour of emulated devices should not depend on the endianness
of the CPU, so avoid using the endian-dependent load and store
functions in the PXA2xx and OMAP display devices. These devices
are little endian when they do DMA access.
(Since ARM softmmu is always compiled as little endian, this means
that the endian-dependent load and store functions are always little
endian, so this commit makes no functionally visible change.)

The ld_raw and st_raw definitions are only needed in code that
must compile for both user-mode and softmmu emulation. Device
models can use the equivalent ld_p/st_p which are simple
pointer accessors.

Many headers are used only in a single directory. These can be
