As all Allwinner platforms are single-cluster A53 chips, we can disable
support for newer, unsupported architecture extensions. We can also
avoid some cache maintenance code, since no platform-specific setup is
required to enable coherency.
These changes reduce the size of .text on a default build with GCC 9.1
enough that .vectors again fits in the second half of a page, instead
of requiring its own page.
This commit was boot-tested on the Pinebook.
