arm64: Add compat hwcap FPHP and ASIMDHP

Browse source

These hwcaps were added earlier for 32-bit native arm kernel by commit
c00a19c8b1 ("ARM: 9268/1: vfp: Add hwcap FPHP and ASIMDHP for FEAT_FP16")
and hence the corresponding changes added in 32-bit compat arm64 kernel for
similar userspace interfaces.

Floating point half-precision (FPHP) and Advanced SIMD half-precision
(ASIMDHP) represents the Armv8 FP16 feature extension and is already
advertised in native arm64 kernel.
