  When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
  bound before relocation. However due to a bug in the DM core,
  the flag only takes effect when devices are statically declared
  via U_BOOT_DEVICE(). This bug has been fixed recently by commit
  "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
  lists_bind_fdt()", but with the fix, it has a side effect that
  all existing drivers that declared DM_FLAG_PRE_RELOC flag will
  be bound before relocation now. This may expose potential boot
  failure on some boards due to insufficient memory during the
  pre-relocation stage.

  To mitigate this potential impact, the following changes are
  implemented:

  - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
  - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
  - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree
