[PATCH] dm: automatically set DM_FLAG_PRE_RELOC based on device-tree property

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>

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.
