riscv: Drop tautological condition from TOOLCHAIN_NEEDS_OLD_ISA_SPEC
Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the Clang dependency part of
CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC is always false, so it can be
removed. Adjust the help text to remove mention of Clang < 17, as it is
irrelevant for the kernel after the minimum supported bump.
