Subject: [PATCH v1] RISC-V: convert new selectors of RISCV_ALTERNATIVE to dependencies

for-next contains two additional extensions that select
RISCV_ALTERNATIVE. RISCV_ALTERNATIVE no longer needs to be selected by
individual config options as it is now selected for !XIP_KERNEL builds
by the top level RISCV option.
These extensions rely on the alternative framework, so convert the
"select"s to "depends on"s instead.

Applies on top of my series doing the aforementioned conversion:
https://lore.kernel.org/all/20230324100538.3514663-3-conor.dooley@microchip.com/

This patch is sent on its own, because I expect the others to be applied
to fixes, as it fixes a v6.3 regression.
For this patch, I applied my other series to v6.3-rc1 and merged that
into for-next, and created this patch on top of the result.
