[PATCH v2 11/22] arm64: dts: ti: k3-am6*: Add boot phase flag to support MMC boot

From: Judith Mendez <jm at ti.com>

The bootph-all flag was introduced in dt-schema
(dtschema/schemas/bootph.yaml) to define node usage across
different boot phases.

For eMMC and SD boot modes, voltage regulator nodes, io-expander
nodes, gpio nodes, and MMC nodes need to be present in all boot
stages, so add missing bootph-all phase flag to these nodes to
support SD boot and eMMC boot.
