There was a workaround in DM that allocates PCI 64bit mem bar in 32bit mem space if the bar size is within 32MB. After the workaround being removed, there is an issue to enter fastboot mode for inappropriate handling of 64bit mem bar in guest driver. The patch bring the workaround back, and skip the workaround when the guest is booted by OVMF. Revert the patch after the guest fixs the issue of handling 64bit mem bar in fastboot mode.
