Revert "mb/google/zork: Increase RO section to 5MB"

This reverts commit fddd101904188193197be10c8eae04e76386299b.

Reason for revert: With FSP compression and non serial FSP we now have enough space in RO.

Original change's description:
> mb/google/zork: Increase RO section to 5MB
>
> The current size is too small to fit all the depthcharge assets.
> Increasing it to 5MB gives us 648k of free space.
