Introduce platform dependent SAGV checking in
combination with bandwidth state pipe SAGV mask.
This is preparation to adding TGL support, which
requires different way of SAGV checking.
v2, v3, v4, v5, v6: Fix rebase conflict
v7: - Nuke icl specific function, use skl
for icl as well, gen specific active_pipes
check to be added in the next patch(Ville)
v8: - Use more generic intel_crtc_can_enable_sagv
for checking(Ville)
