Message:

Improve early kernel debugging prints

Since the early kernel debugging prints are useful only in a few
debugging scenarios, define a configuration option that disables them by
default (if enabled, it produces duplicate output which might be
confusing).

Implement early kernel debugging prints for the HiKey960.
