Thomas Zimmermann 202fb33be3 drm/ast: Avoid reprogramming primary-plane scanout address ...

Some AST-based BMCs stop display output for up to 5 seconds after
reprogramming the scanout address. As the address is fixed, avoid
re-setting the address' value.

v2:
	* only update offset if it changed (Jocelyn)
