target/riscv: use misa_mxl_max to populate isa string rather than TARGET_LONG_BITS
A cpu may not have the same xlen as the compile time target, and
misa_mxl_max is the source of truth for what the hart supports.
The conversion from misa_mxl_max to xlen already has one user, so
introduce a helper and use that to populate the isa string.
