riscv: Fix build errors using binutils2.37 toolchains

commit ef21fa7c198e04f3d3053b1c5b5f2b4b225c3350 upstream.

When building the kernel with binutils 2.37 and GCC-11.1.0/GCC-11.2.0,
the following error occurs:

  Assembler messages:
  Error: cannot find default versions of the ISA extension `zicsr'
  Error: cannot find default versions of the ISA extension `zifencei'

The above error originated from this commit of binutils[0], which has been
resolved and backported by GCC-12.1.0[1] and GCC-11.3.0[2].

So fix this by change the GCC version in
CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC to GCC-11.3.0.
