One needs to set u-boot,dm-pre-reloc in a device Device Tree node so that it is kept in SPL/TPL variant of the device tree. However, a device is automatically probed only if it's flagged with DM_FLAG_PRE_RELOC, regardless of u-boot,dm-pre-reloc DT property presence. This flag is currently only set by drivers directly.
However, this flag should be allowed to be set on a per-device basis even if the driver does not hardcode it so that the device will be probed in SPL/TPL regardless of the driver's defaults.
This sets the DM_FLAG_PRE_RELOC for all U_BOOT_CLASS devices whose DT node contains the u-boot,dm-pre-reloc property.
