Add a dts fragment file to support the sc7180 boards with the second
source edp bridge, Parade ps8640.
Signed-off-by: Philip Chen <philipchen@xxxxxxxxxxxx>
---
Changes in v3:
- Set gpio32 active high
- Rename edp-bridge to bridge to align with ti-sn65 dts
- Remove the unused label 'aux_bus'
Changes in v2:
- Add the definition of edp_brij_i2c and some other properties to
ps8640 dts, making it match ti-sn65dsi86 dts better
