[PATCH v9 9/9] arm64: dts: ti: Add wkup 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.

Add the bootph-pre-ram flag to the wkup_r5fss0_core0 node in both
ipc-firmware dtsi files and to the lpm metadata region nodes of the
AM62A and AM62P boards.

The board level bootph-pre-ram flag of k3-am62d2-evm.dts becomes
redundant with the dtsi-wide flag and is dropped.
