U-Boot Driver Model is supposed to remove devices with either DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting. Our bootm command does that by explicitly calling calling "dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any USB devices. The EFI equivalent is doing none of those at the moment. As a result probing an fTPM driver now renders it unusable in Linux. During our (*probe) callback we open a session with OP-TEE, which is supposed to close with our (*remove) callback. Since the (*remove) is never called, once we boot into Linux and try to probe the device again we are getting a busy error response. Moreover all uclass (*preremove) functions won't run. So let's fix this by mimicking what bootm does and disconnect devices when efi_exit_boot_services() is called.
