[RFC PATCH 3/6] arm: dts: k3-j784s4-main: Add clock and power domains for MAIN_R5_2_x

Add bootph-pre-ram as well as the clocks and power-domains for
MAIN_R5_2_x. This ensures that LPSC sets the appropriate power and clock
and allows for BIST to turn the cores on and off for running the
self-test at R5 SPL stage.
