Support Qualcomm Kryo 385 CPU variant.
Support Kryo 385 cpu variant which should be used for
Qualcomm Snapdragon 845.
Motivation:
kryo385 CPU *IS NOT* an Arm Cortex-A75.
Particular problem:
Cortex-A75 CPU must support optional ARMv8.2 dot product
feature; kryo385 CPU (Qualcomm Snapdragon 845) doesn't
support it.
Test: Builds when kryo385 is used as cpu variant.
Test: Pixel 3 boots to GUI with kryo385 as CPU variant
with this patch on AOSP 9.0.0 r16.
