msm: mdss: Fix the DSI lane swap programming logic
In the current programming sequence, if a particular logical lane
is not used, we map the corresponding physical lane for this to '0';
which means no connection. This can cause DSI FIFO overflow issues
for panels which don't use all the 4 lanes. Fix this by programming
the LOGICAL_LANE_SWAP_CTRL for all the 4 lanes always, irrespective
of the number of lanes used.
