mpegplayer: Fix aliasing rules violation on multi-core targets
As the PP series has no sense of cache coherency between its multiple
cores, we need to ensure the vo_data structure does not share cachelines
with anything else.
This was previously done by defining a uint8_t array and trying to
access it via typecasting hell, triggering a large pile of aliasing
violation warnings on newer toolchains and/or higher optimization
levels.
Instead of violating the C spec in an undefined-behaviour-sort-of-way,
create a union of the right size and alignment, and make one of its members
the structure we care about. Voila, everyone is happy.
