Introduce k3-j721e-r5.dtsi to be used by board R5 DTS files. This
helps sync SoC changes across boards.

I think I just noticed that this node is only enabled in R5 dts for
j721e, though not required for cleanup in this series as we'll be
porting these tags to kernel anyways but the node is marked with
bootph-all in -u-boot.dtsi and the pins are only marked bootph-pre-ram.
Might be good to look at some other tags as well while porting these to
kernel [0].

Rest LGTM.
