Subject: [PATCH v2] drm/bridge: parade-ps8640: Reorg the macros

Reorg the macros as follows:
(1) Group the registers on the same page together.
(2) Group the register and its bit operation together while indenting
the macros of the bit operation with one space.

Also fix a misnomer for the number of mipi data lanes.

Signed-off-by: Philip Chen <philipchen@...omium.org>

Changes in v2:
- Fix the double sign-off lines
