arm: dts: k3-am642-*: Mark the memory node with u-boot, dm-spl Since commit dffdb1f8eb ("board: ti: am64x: Use fdt functions for ram and bank init") ddr_init() and dram_bank_init() have switched to fdtdec for getting the memory configuration from the am64xx dts files instead of using hardcoded values. This requires an accessible memory node in SPL as we already have in k3-am642-r5-evm.dts. Make the memory node accessible in A53 SPL for both am642-sk and am642-evm and in am642-sk R5 SPL.
