hw/display/pl110: Pull included-once parts of template header into pl110.c
The pl110_template.h header has a doubly-nested multiple-include pattern: * pl110.c includes it once for each host bit depth (now always 32) * every time it is included, it includes itself 6 times, to account for multiple guest device pixel and byte orders Now we only have to deal with 32-bit host bit depths, we can move the code corresponding to the outer layer of this double-nesting to be directly in pl110.c and reduce the template header to a single layer of nesting.
