target-arm: Correct Cortex-A57 ISAR5 and AA64ISAR0 ID register values
We implement the crypto extensions but were incorrectly reporting
ID register values for the Cortex-A57 which did not advertise
crypto. Use the correct values as described in the TRM.
With this fix Linux correctly detects presence of the crypto
features and advertises them in /proc/cpuinfo.
