riscv: hwprobe: Add SiFive vendor extension support and probe for xsfqmaccdod and xsfqmaccqoq

Add a new hwprobe key "RISCV_HWPROBE_KEY_VENDOR_EXT_SIFIVE_0" which allows
userspace to probe for the new vendor extensions from SiFive. Also, add
new hwprobe for SiFive "xsfvqmaccdod" and "xsfvqmaccqoq" vendor
extensions.
