Subject: [PATCH v2 2/5] arm64: dts: ti: k3-am62a-phycore-som: Add boot phase tags

The bootph-all and bootph-pre-ram tags were introduced in dt-schema
(dtschema/schemas/bootph.yaml) to define node usage across different
boot phases.

Add boot phase tags to all required nodes to ensure boot support from
all sources, including UART, USB (DFU), Ethernet, uSD card, eMMC, and
OSPI NOR Flash.

Signed-off-by: Wadim Egorov <w.egorov@...tec.de>
