arm64: dts: ti: k3-am68-sk*: Add bootph-* properties

Browse Source 
Adds bootph-* properties to the leaf nodes to enable bootloaders to
utilise them.

Following adds bootph-* to:
- main_uart8, mcu_uart0(DM), wkup_uart0(TIFS) for Traces
- mmc1, ospi0 for enabling various bootmodes.
- eeprom for board detection
