Subject: [PATCH] arm64: dts: ti: Add phase tags for memory node on J784S4 EVM and AM69 SK

memory node are required for bootloader operation on TI K3 J784S4 EVM
and AM69-SK boards for finding the memory size during early boot stage.

So, align Linux device tree by adding phase tag marking 'bootph-all',
which is to enable for all bootloader stages.
