8f4d2683b0 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

1381308bb1 drm/i915: wait for all DSI FIFOs to be empty
Ensure that the DSI packets for a particular sequence are completely
sent before going ahead in the enabling or disabling of the panel

This fixes a printf warn from gcc:

drivers/gpu/drm/i915/intel_dsi_cmd.c: In function ‘dsi_vc_send_long’:
drivers/gpu/drm/i915/intel_dsi_cmd.c:181:2: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 7 has type ‘size_t’ [-Wformat=]

69c05eb2d8 drm/i915: add MIPI DSI command sending routines
v2: Rebase due to register bit definition change.

v3: Mostly based on Ville's review comments.
 - Use size_t for length all around.
 - Reuse dsi_vc_send_short in dsi_vc_send_long.
 - Remove stale/incorrect comments.
 - Reverse special packet sent interrupt check.
 - Use DSI controller regs for reading, not adapter.
