That's because commit 9e644284 ("dm: core: Report
bootph-pre-ram/sram node as pre-reloc after relocation"):

	"[This] changes behavior of what nodes are bound in the U-Boot
	proper pre-relocation phase. Change to bootph-all or add
	bootph-some-ram prop to restore prior behavior."

Fix this by adding bootph-some-ram prop as suggested by the commit
above.
