Increase size of the coreboot table area 

Packing a device tree into the coreboot table can easily make
the table exceed the current limit of 8KB. However, right now
there is no error handling in place to catch that case.

Increase the maximum memory usable for all tables from 64KB to
128KB and increase the maximum coreboot table size from 8KB
to 32KB.
