(1 << 31) is a signed negative integer, and it was sign-extended when
being or'ed into the "missing" variable. This casues hwprobe not
reflecing extensions named after RISCV_HWPROBE_EXT_ZVFHMIN. Fix it by
defining it as a unsigend long long.
Fixes: 5dadda5e6a59 ("riscv: hwprobe: export Zvfh[min] ISA extensions")
