drm/i915: Redo intel_tile_height() as intel_tile_size() / intel_tile_width()
I find more usual to think about tile widths than heights, so changing
the intel_tile_height() to calculate the tile height as
tile_size/tile_width is easier than the opposite to the poor brain.
v2: Reorder arguments for consistency
Constify dev_priv arguments
