[PATCH v2 4/7] qfw: Add flag to allow probing before relocation

[Alper Nebi Yasak]

QEMU firmware config drivers need to be probed to bind the ramfb device.
The ramfb driver needs to be bound before relocation to properly reserve
video memory for it, otherwise it cannot be probed after relocation. Add
the flag to probe QEMU firmware config drivers before relocation so that
ramfb can work as an initial vidconsole.

Alternatively, I guess I could default VIDEO_PCI_DEFAULT_FB_SIZE to a
higher size with "if VIDEO_RAMFB". But it exists because "PCI drivers
cannot be bound before relocation unless they are mentioned in the
devicetree" and qfw is in the QEMU-generated devicetree unlike those, so
I assumed this would be the preferred way.

Changes in v2:
- Add patch "qfw: Add flag to allow probing before relocation"
