gfx: Move drivers/generic/gfx to drivers/gfx/generic

This change creates gfx directory under drivers/ so that all drivers
handling gfx devices can be located in the same place. In follow-up
CLs, we will be adding another driver that handles gfx devices.

This change also updates the names used within the driver from
*generic_gfx* to *gfx_generic*. In addition to that, mainboard
drallion using this driver is updated to match the correct path and
Kconfig name.

TEST=Verified that drallion still builds.
