Add *_current definitions for currently-defined Hostboot BIOS attributes

This commit adds hb_*_current attributes for currently-defined
"latched" Hostboot BIOS attributes. Certain hb_* BIOS attributes will
be copied into the hb_*_current attributes at the beginning of each
IPL to indicate what value is in use for the IPL after it is complete.
