arm64: Add compat hwcap ASIMDFHM
This hwcap was added earlier for 32-bit native arm kernel by commit
ce4835497c20 ("ARM: 9270/1: vfp: Add hwcap for FEAT_FHM") and hence the
corresponding changes added in 32-bit compat arm64 kernel for similar user
interfaces.
Floating-point half-precision multiplication (FHM) is a feature present
in AArch32/AArch64 state for Armv8. This hwcap is already advertised in
native arm64 kernel.
