Adds bootph-* properties to the leaf nodes to enable bootloaders to
utilise them.
Following adds bootph-* to
- System controller nodes that allow controlling power domain, clocks, etc.
- secure_proxy_sa3/secure_proxy_main mboxes for communication with
System Controller
- mcu_ringacc/mcu_udmap for DMA to SMS
- chipid for detection soc information.
- mcu_timer0 for bootloader tick-timer.
- wkup_vtm for enabling Adaptive voltage scaling(AVS) support
