[PATCH v3 01/10] dt-bindings: display: panel: s6e3ha8: Adjust to reflect the DDIC and panel used

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@xxxxxxx>

S6E3HA8 is the DDIC, while the panel used on the Samsung Galaxy S9 is
the Samsung AMB577PX01. Introduce a compatible reflecting that, adjust
the example, and deprecate the DDIC-only samsung,s6e3ha8 compatible.

We're going to introduce another panel with different sequence, so keep
calling original panel sequence just by the DDIC name is confusing.
While we at it, we can cleanly fix reversed GPIO polarity.

Update the polarity to better match newly introduced compatibles with
fixed logic.
