fix(qemu): increase max FIP size

The max FIP size for the QEMU virt platform is currently 4MB, which
isn't enough when including a RMM in the FIP. Since the secure flash
size is actually 64MB, we can significantly increase the max FIP size.

Change-Id: Id2b5df355f8d4c90a41fec66f180e46eb7bab9f8
Fixes: a886bbeceb0d ("qemu: Update flash address map to keep FIP in secure FLASH0")
