RISC-V: remove toolchain version checks for Zicbom
Commit b8c86872d1dc ("riscv: fix detection of toolchain Zicbom
support") fixed building on systems where Zicbom was supported by the
compiler/assembler but not by the linker in an easily backportable
manner.
Now that the we have insn-defs for the 3 instructions, toolchain support
is no longer required for Zicbom.
Stop emitting "_zicbom" in -march when Zicbom is enabled & drop the
version checks entirely.
