[Buildroot] [PATCH v3] boot/riscv-pk: Remove obselete bootloader

[Alistair Francis]

The RISCV Proxy Kernel (AKA BBL) isn't being used by most distros so has
very limited testing. It has been replaced by OpenSBI and been
deprecated for awhile, so let's just remove it.

 Since Mark gave the go in the end, I applied to master, thanks.

 Normally, for legacy symbols, we automatically select the replacement. So in
this case, we could add 'select BR2_TARGET_OPENSBI' here. However, since the
target platform still has to be specified, doing it automatically doesn't make a
whole lot of sense.
