arm64: __flush_dcache_area to take end parameter instead of size
To be consistent with other functions with similar names and
functionality in cacheflush.h, cache.S, and cachetlb.rst, change
to specify the range in terms of start and end, as opposed to
start and size.
No functional change intended.
