drm/i915/skl: Extract tile height code into a helper function
It will be used in a later patch and also convert all height parameters
from int to unsigned int.
v2: Rebased for fb modifiers.
v3: Fixed v2 rebase.
v4:
* Height should be unsigned int.
* Make it take pixel_format for consistency and simplicity.
