drm/i915: Added port as parameter to the functions which does read/write of DSI Controller
This patch is in preparation of DSI dual link panels. For dual link
panels, few packets needs to be sent to Port A or Port C or both. Based
on the portno from MIPI Sequence Block#53, these sequences needs to be
sent accordingly.
v2: Addressed review comments by Jani
- port variables named properly
