Subject: [PATCH v5 03/12] arm64: dts: ti: k3-j784s4: Add bootph-*
 properties

The following nodes are being used in the bootloaders. Adds bootph-*
properties to the leaf nodes to enable bootloaders to utilise them.

Following adds bootph-* to
- secure_proxy_sa3/secure_proxy_main mboxes for communication with
  System Controller
- wkup_vtm for enabling Adaptive voltage scaling(AVS) support
