arm: h264chroma: Do not compile h264_chroma_mc* dependent on h264 decoder
...
The functions are used by all codecs that enable the h264chroma component
and the file is already compiled conditional on h264chroma being enabled.

ARM: fix overreads in neon h264 chroma mc
...
The loops were reading ahead one line, which could end up outside the
buffer for reference blocks at the edge of the picture. Removing
this readahead has no measurable performance impact.

ARM: use standard syntax for all LDRD/STRD instructions
...
The standard syntax requires two destination registers for
LDRD/STRD instructions. Some versions of the GNU assembler
allow using only one with the second implicit, others are
more strict.
