riscv: Add Ziccamoa, Ziccif, Ziccrse, and Za64rs to cpufeature and hwprobe
Add Ziccamoa, Ziccif, and Za64rs to riscv_isa_ext[] so they can be
parsed from devicetree/ACPI ISA strings. Ziccrse is already present
in cpufeature; this patch only adds its hwprobe exposure.
Expose all four extensions via hwprobe through new bits in
RISCV_HWPROBE_KEY_IMA_EXT_1 (RISCV_HWPROBE_EXT_ZICCAMOA, _ZICCIF,
_ZICCRSE, _ZA64RS), so userspace can probe each of these
RVA23U64-mandatory extensions individually.
