lib/lzo: Update LZO compression to current upstream version

This commit updates the kernel LZO code to the current upsteam version
which features a significant speed improvement - benchmarking the Calgary
and Silesia test corpora typically shows a doubled performance in
both compression and decompression on modern i386/x86_64/powerpc machines.

ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

Enable UNALIGNED_ACCESS for the new LZO algorithm to use. LZO decrompression is used on QCACHE so we benefit a little from the new and improved LZO code.

Add Gamma Control v1. Thanks to @paranoidandroid for researching what each gamma value changed so that I could build this interface. It enables the possibility of tweaking whites, mids, blacks, contrast, saturation, brightness and greys. This is a full GPL'ed code and easy to use for any user without any special mumbo jumbo.

Moto screen driver is too different, need more time to figure out.
