dibbi: Increase heap size

The firmware screens are missing text when using a Type-C external
display, due to an allocation failure when loading the firmware screen
files from CBFS. Increase the heap size to avoid running out of memory.
This is the same as how CL:2491381 fixed the same issue on volteer.

BRANCH=dedede
BUG=b:283196347
