riscv: Require FRAME_POINTER for some configurations
Some V configurations implicitly turn on '-fno-omit-frame-pointer',
but leaving FRAME_POINTER disabled. This makes it hard to reason about
the FRAME_POINTER config, and also triggers build failures introduced
in by the commit in the Fixes: tag.
Select FRAME_POINTER explicitly for these configurations.
Fixes: ebc9cb03b21e ("riscv: stack: Fixup independent softirq stack for CONFIG_FRAME_POINTER=n")
