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")

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