Until now, all platform that supported both eDP and DP had different
compatibles for each mode. Using different compatibles for basically
the same IP block but for a different configuration is bad way all
around. There is a new compute platform from Qualcomm that supports
both eDP and DP with the same PHY. So instead of following the old
method, we should allow the mode to be configured via set_mode from
the controller driver.

The controller part will follow after we conclude the PHY part first.

Changes in v2:
- Dropped the dedicated xlate function and added set_mode op instead
- Dropped the eDP PHY type and mode addition
- Added the DP PHY submodes (eDP and DP)
- Removed the device match data storing from the container struct
- Link to v1: https://lore.kernel.org/r/20231219-x1e80100-phy-edp-compatible-refactor-v1-0-f9e77752953d@linaro.org

Initial attepmpt was here:
https://lore.kernel.org/all/20231122-phy-qualcomm-edp-x1e80100-v3-3-576fc4e9559d@linaro.org/
Compared to that version, this one uses the phy-cells method and drops
the X1E80100 support. The X1E80100 support will be a separate patchset.
