symbols: add '_' to pci_drivers and cpu_drivers symbols

In order to prepare for more unification of the linker
scripts prefix pci_drivers, epci_drivers, cpu_drivers, and
ecpu_drivers with an underscore.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built different boards includes ones w/ and w/o relocatable
     ramstage.
