[PATCH 22/78] ARM: aarch64: fix early cache flushing

[Sascha Hauer]

v8_dcache_all() should not be used directly, but only called from
v8_flush_dcache_all() and v8_invalidate_dcache_all() which set
pass the type of operation in x0. While at it add the missing prototype
for v8_invalidate_dcache_all().
