drm/i915: Add sprite watermark programming for VLV and CHV

Program DDL register as part of sprite watermark programming for CHV and VLV.

v2: Rename DRAIN_LATENCY_MAX by DRAIN_LATENCY_MASK

v3: Addressed review comments by Ville
    - Changed Sprite DDL definitions to more generic to avoid multiple if-else
    - Changed bit masking to customary form
    - Changed to bitwise shorthand operator for sprite_dl assignment
