gma pipe_setup: Replace Update_Offset() with Setup_FB()

Beside updates to the framebuffer offset in memory, Setup_FB() allows
changes to size, position, tiling and rotation, too. Basically every-
thing but changes to BPC (which would need an update in the transcoder
configuration on pre-Broadwell hardware, too).

It is not clear if the updates work fully synchronous on all hardware
generations. Though, tests on APL have shown a glitch free transition
so far.
