Description

MFC r347225:

Provide a template for busdma code for RISC-V.

RISC-V ISA specifies no cache management instructions so leave cache
operations in cpufunc.h as no-op for now.

Note some new hardware comes with their own memory-mapped cache
management controller.

Tested on HiFive Unleashed board with cgem(4).
