A larger EFI file system size will facilitate multi-boot configurations and the installation other EFI applications like firmware update tools. 200MB matches OS X. Note that this changes only the partition size, not the file system that bsdinstall places there. We need to do both, but as the partition size is difficult to adjust later make this change for now so that at least systems installed with FreeBSD 11.0 have a partition layout with room to grow.
