Subject: [PATCH v5 12/12] arm64: dts: ti: k3-j7200-evm*: Add bootph-*
properties
Adds bootph-* properties to the leaf nodes to enable bootloaders to
utilise them.
Following adds bootph-* to:
- pmic regulator for enabling AVS Support
- main_uart0, mcu_uart0(DM), wkup_uart0(TIFS) for Traces
- mmc0, mmc1, usb0, ospi0, ospi1, hbmc for enabling various bootmodes.
