drm/i915: Add function to check for linear surfaces

Browse Source 
A framebuffer can comprise surfaces with distinct tiling formats,
making checks against modifier alone insufficient. Make use of a
function to identify a linear surface based on both modifier and color
plane.

v2: Typo fix
v3: remove 'inline' from function definition (Ville)
