Replace UNPACK_CB64 macro with inline 

Having submitted a module based on coreboot to LKML for acceptance,
it was requested that fewer macros and more inlines be used (because
of their superior type-checking when performing pointer casts, etc).

This is the first of several changes to make the relevant parts of
coreboot comply to linux code standards.
