riscv: Add runtime constant support

Browse source

Implement the runtime constant infrastructure for riscv. Use this
infrastructure to generate constants to be used by the d_hash()
function.

This is the riscv variant of commit 94a2bc0f61 ("arm64: add 'runtime
constant' support") and commit e3c92e8171 ("runtime constants: add
x86 architecture support").
