[PATCH v3 02/15] riscv: hwprobe.rst: Document EXT_ZICFISS and EXT_ZICFILP

Commit 30c3099036a9 ("riscv/hwprobe: add zicfilp / zicfiss
enumeration in hwprobe") added RISCV_HWPROBE_EXT_ZICFISS and
RISCV_HWPROBE_EXT_ZICFILP, but did not add matching entries to
Documentation/arch/riscv/hwprobe.rst.  Add them now.

Fixes: 30c3099036a9 ("riscv/hwprobe: add zicfilp / zicfiss enumeration in hwprobe")

v3:
- Also document RISCV_HWPROBE_EXT_ZICFILP (bit 63 of IMA_EXT_0), the
  sibling enumeration added by the same commit (Andrew).
v2: New patch.
