Eliminate use of pointers in coreboot table

Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.
