drm/i915: Replace wm.max_levels with wm.num_levels and use it everywhere
Replaces wm.max_level with wm.num_levels, since that generally
results in nicer looking code (for-loops can be in standard
form etc.).
Also get rid of the two different wrappers we have for this
(ilk_wm_max_level() and intel_wm_num_levels()). They don't
really do anything for us other than potentially slow things
down if the compiler actually emits the function calls every
time (num_planes*num_wm_levels*higher_level_wm_function_calls
could be a big number). The watermark code already shows up
far too prominently in cpu profiles. Though I must admit that
I didn't look at the generated code this time.
v2: Fix the ilk_wm_merge() off-by-one (Jani)
