James Morse 1bdb0fbb2e arm64: errata: remove BF16 HWCAP due to incorrect result on Cortex-A510 
Cortex-A510's erratum #2658417 causes two BF16 instructions to return the
wrong result in rare circumstances when a pair of A510 CPUs are using
shared neon hardware.

The two instructions affected are BFMMLA and VMMLA, support for these is
indicated by the BF16 HWCAP. Remove it on affected platforms.
