arm64: dts: ti: Add bootph property to nodes at source for am62a

Add bootph property directly into the original definitions of relevant
nodes (e.g., power domains, USB controllers, and other peripherals)
within their respective DTSI files (ex. main, mcu, and wakeup) for
am62a.

By defining bootph in the nodes source definitions instead of appending
it later in final DTS files, this change ensures that the property is
inherently present wherever the nodes are reused across derived device
trees.
