soc/intel/apollolake: dump CSE status

Dump the CSE status registers for potential debugging purposes.
Explicitly call out manufacturing mode of the part since it's
important shipping devices ensure manufacturing mode is locked
down. Intel is planning on writing a common driver so a complete
status -> string dumps was not done because (surprise surprise)
not all the fields are equal with previous implementations.

BUG=chrome-os-partner:62177
BRANCH=reef
TEST=Booted and noted dump of CSE status registers.
