[PATCH v4 8/9] hwprobe: fix integer promotion in RISCV_HWPROBE_EXT macro

[Andy Chiu]

(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.
