Log message:
T-Head implemented a page attribute extension that violates the RISC-V
specification. The default attributes result in memory being uncached
which makes the system perform like a slug. So implement a workaround
that is designed to make implementation of the Svpbmt extension that is
part of the latest published RISC-V specification. This gets us a bit
further booting OpenBSD on an Allwinner D1 SoC.
