drm/i915/display: Simplify intel_joiner_num_pipes and its usage

Browse Source 
Currently intel_joiner_num_pipes is used to get num of pipes wrt num of
pipes joined. Simplify this by returning 1 when no joiner is used and
update the checks for no joiner case.

v2: Rename the function to intel_crtc_num_joined_pipes and use helper
intel_crtc_joined_pipe_mask. (Ville)
