OvmfPkg/QemuVideoDxe: unbreak "secondary-vga" and "bochs-display" support
In edk2 commit 333f32ec23dd, QemuVideoDxe gained support for QEMU's
"secondary-vga" device model (originally introduced in QEMU commit
63e3e24db2e9).
In QEMU commit 765c94290863, the "bochs-display" device was introduced,
which would work with QemuVideoDxe out of the box, reusing the
"secondary-vga" logic.
Support for both models has been broken since edk2 commit 662bd0da7fd7.
Said patch ended up requiring VGA IO Ports -- i.e., at least one of
EFI_PCI_IO_ATTRIBUTE_VGA_IO and EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 -- even if
the device wasn't actually VGA compatible.
Restrict the IO Ports requirement to VGA compatible devices.
