drm/i915: Simplify intel_cx0_program_phy_lane() with loop

It is possible to generalize the "disable" value for the transmitters to
be a bit mask based on the port width and the port reversal boolean,
with a small exception for DP-alt mode with "x1" port width.

Simplify the code by using such a mask and a for-loop instead of using
switch-case statements.

v2:
  - Use (i < 2) instead of (i / 2 == 0) for PHY lane mask selection.
