[PATCH 5/6] arm64: dts: ti: k3-am62a7-sk: Add r5f nodes to pre-ram bootphase

[Markus Schneider-Pargmann (TI)]

For IO+DDR the wkup_r5fss0_core0 and the
wkup_r5fss0_core0_lpm_metadata_region need to be accessed before RAM
setup is done. These are used to read the lpm metadata region in which
data is stored to resume. This needs to be done before RAM is in use to
avoid overwriting data.
