riscv: integrate alternatives better into the main architecture
Right now the alternatives need to be explicitly enabled and
erratas are limited to SiFive ones.
We want to use alternatives not only for patching soc erratas,
but in the future also for handling different behaviour depending
on the existence of future extensions.
So move the core alternatives over to the kernel subdirectory
and move the CONFIG_RISCV_ALTERNATIVE to be a hidden symbol
which we expect relevant erratas and extensions to just select
if needed.
