[libvirt] [PATCH 2/6] bhyve: add support for booting from UEFI

From: Fabian Freyer <fabian.freyer at physik.tu-berlin.de>
Allow to boot using UEFI rather than using an external boot loader
such as bhyveload or grub-bhyve.
Also, make LPC PCI-ISA bridge handling more flexible as now it's
needed not only for serial ports, but for bootrom as well.
