Subject: [PATCH v2 07/11] drm/panel: Add panel driver for Samsung SOFEF03-M
 DDIC

The SOFEF03-M Display-Driver-IC is paired with a amb609vp01 panel on
the Sony Xperia 5 II and amb609vp04 panel on the Sony Xperia 5 III. It
requires Display Stream Compression 1.1 which allows the panels to run
at 120Hz, even though a 60Hz mode is available too.

Downstream porch values are retained; despite not being used in
command-mode they are useful to artificially bump the clock values to
account for "transfer overhead" while that calculation is still missing
from the MSM DSI host driver.
