[Intel-gfx] [i-g-t PATCH v4 3/4] kms_flip: set VT graphics mode

[Imre Deak]

This is one reason for some of the sporadic kms_flip failures.
One such is https://bugs.freedesktop.org/show_bug.cgi?id=59834.

v2:
- use unsigned long for KDSETMODE/KDGETMODE
- fix passing the parameter to KDGETMODE as it should be by value
- actually testing that it works..

v3:
- don't do an explicit DPMS_ON, only switch to graphics mode.

v4:
- use the newly added drmtest_set_vt_graphics_mode(), which will also
  take care of restoring the original mode. (Daniel)
