Matthew Brecknell d1ffbe0ad6 riscv: use uint8_t for register_t 
`register_t` only needs to be able to index into the TCB user context
array, which has 35 entries. Therefore `uint8_t` is sufficient.

Using the smallest possible type for `register_t` helps with binary
verification. This shrinks static read-only data, which in turn reduces
the complexity of binary verification proof search.
