Since commit 9e644284ab81 ("dm: core: Report bootph-pre-ram/sram node as pre-reloc after relocation"), bootph-pre-ram doesn't make U-Boot proper bind the device before relocation.
While this is usually not much of an issue, it is when there's a lookup for devices by code running before the relocation. Such is the case of env_init() which calls env_driver_lookup() which calls env_get_location() which is a weak symbol and may call arch_env_get_location() also a weak symbol. Those are two functions that may traverse UCLASS to find some devices (e.g. board/theobroma-systems/common/common.c:arch_env_get_location()).
This allows something in the env_init() call stack to be able to use uclasses for SD and eMMC controller on RK3588S/RK3588. This aligns the behavior with what seems to be all SoCs except RK356x family.
Additionally, if any other env function (e.g. env_load) were to be used before relocation, this is also required as otherwise it wouldn't be able to find the MMC device(s).
