RISC-V: Add auxiliary files

Browse source 
To support a new architecture we need to provide a few helper functions
for memory, cache, timer, etc support.

This patch adds the remainders of those. Some bits are still disabled,
as I couldn't guarantee that we're always running on models / in modes
where the respective hardware is available.
