[PATCH v3 0/1] RISC-V: Add SpacemiT vendor extensions xsmtvdot

[Mark Zhuang]

From: Mark Zhuang <mark.zhuang@spacemit.com>

Thanks Jan for the helpful review, the suggestions really improved things.

Changes in v3:
  - Fix gas/NEWS placement
  - Fix indentation, line length and comment style issues.
  - Drop riscv_smt_wi table, parse width specifiers inline.
  - Make Xpw&8 an optional operand, remove INSN_ALIAS duplicates.
