Update to the sysutils/uefi-edk2-bhyve and related ports

[Rebecca Cran]

Hi,


I'd like to get some more testing of the new UEFI EDK2 port before I 
hopefully commit it next week.

The diff can be downloaded from https://reviews.freebsd.org/D27230 
(click "Download raw diff" on the right-hand side). It deletes the 
uefi-edk2-bhyve-devel port, copies the current uefi-edk2-bhyve port into 
uefi-edk2-bhyve-csm and makes it only build with CSM support, and 
updates the uefi-edk2-bhyve port to build with recent code from 
https://github.com/tianocore/edk2/tree/master/OvmfPkg/Bhyve .


Both testing of the BhyveX64 firmware and review feedback on the port 
changes would be welcome. There's an upstream edk2-stable202011 tag 
coming up soon, and I'd like to fix any issues in time for that.
