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.

riscv: hwprobe: Add thead vendor extension probing2025-01-18T20:33:35ZCharlie Jenkinscharlie@rivosinc.com2024-11-14T02:21:16Zurn:sha1:a5ea53da65c588339890c825e63c0da5baef6897
Add a new hwprobe key "RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0" which
allows userspace to probe for the new RISCV_ISA_VENDOR_EXT_XTHEADVECTOR
vendor extension.
This new key will allow userspace code to probe for which thead vendor
extensions are supported. This API is modeled to be consistent with
RISCV_HWPROBE_KEY_IMA_EXT_0. The bitmask returned will have each bit
corresponding to a supported thead vendor extension of the cpumask set.
Just like RISCV_HWPROBE_KEY_IMA_EXT_0, this allows a userspace program
to determine all of the supported thead vendor extensions in one call.
