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.

Note that this may have undesirable results in the USB subsystem as
it causes unplugged devices to linger around in the dm-tree, and it
causes USB host controllers to not be stopped when booting the OS.
