PATCH: Increase System Firmware Max Size

[McMillan, Erich]

Hi all,

(this is my first Qemu patch submission, please let me know if my formatting/content needs to be fixed).

We have a need for increased firmware size, currently we are building Qemu with the following change to test our Uefi Firmware and it works well for us. Hope that this change can be made to open source. Thank you.

-------

Increase allowed system firmware size to 16M per comment suggesting up to 18M is permissible.
