[PATCH v11 03/24] dt-bindings: ufs: mediatek,ufs: Add mt8196 variant

[Louis-Alexis Eyraud <louisalexis.eyraud@collabora.com>]

From: Nicolas Frattaroli <nicolas.frattaroli@collabora.com>

The MediaTek MT8196 SoC's UFS controller uses a different set of supplies.
It is therefore not compatible with the MT8195. It also have an additional
0.9V supply pin (AVDD09_UFS_1), that is specific to this SoC, thus not
currently described in the binding.

Add a compatible for this SoC and new property for the additional supply,
and modify the binding correspondingly.
