[U-Boot] [PATCH v3 17/19] drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the Kconfig

It is currently not possible to include the support to remove devices in
the SPL. This is however needed by platforms that re-select their dtb after
DM is initialized; they need to remove all the previously bound devices
before triggering a scan of the new DT.

Add a Kconfig option to be able to include the support for device removal
in the SPL.
