cpu: Drop "extern" from function declarations in cpuhplock.h

This file was created with a direct cut and paste from cpu.h so
kept the legacy declaration style.

But the Linux coding standard for function declarations in header
files is to avoid use of "extern".

Drop "extern" from all function declarations.
