[PATCH 1/2] dt-bindings: drm: bridge: adi, adv7533: Document adi, disable-lanes-override property

[Biju Das]

On Renesas RZ/{G2L,V2L} platforms changing the lanes from 4 to 3 at
lower frequencies causes display instability. On such platforms, it
is better to avoid switching lanes from 4 to 3 as it needs different
set of PLL parameter constraints to make the display stable with 3
lanes.

This patch introduces 'adi,disable-lanes-override' property to disable
lane switching at lower frequencies.
