[PATCH] dt-bindings: mfd: mediatek,mt6357: Fixup reference to pwrap node

[Macpaul Lin <macpaul.lin@mediatek.com>]

The mt6357 is a subnode of pwrap node. Previously, the documentation
only included a note in the description of mt6357. This change adds the
appropriate $ref for pwrap to ensure clarity and correctness.

  $ref: /schemas/soc/mediatek/mediatek,pwrap.yaml

Additionally, the indentation for the pmic section has been adjusted
to match the corresponding structure.
