aarch64: Remove AARCH64_FEATURE_F16 from AARCH64_ARCH_V8_2

Browse source 
The FP16 feature is optional in ARMv8.2, so it is wrong to add it to
the default AARCH64_ARCH_V8_2 feature flags.  This patch makes the
behaviour consistent with that of gcc, which also does not assume FP16
for ARMv8.2.

	* opcode/aarch64.h (AARCH64_ARCH_V8_2): Drop
	AARCH64_FEATURE_F16.
