libgfxinit: Allow to configure screen rotation

This allows to configure a default screen rotation in 90-degree
steps. The framebuffer contents will then be displayed rotated,
by the same amount in the other direction; i.e. if you turn the
screen to the left, the picture has to be rotated to the right
to accommodate.

This is only supported by libgfxinit from Skylake / Apollo Lake
on (earlier GPUs didn't support the 90-degree steps anyway) and
it only works with the linear-framebuffer option.
