From: Bean Huo <beanhuo@micron.com>

In 'include/ufs/ufshcd.h' file, 'enum dma_data_direction' will be used,
which is defined in linux/dma-direction.h, however, this header file is
not included in ufshcd.h, thus causing the following compilation warning:

"warning: ‘enum dma_data_direction’ declared inside parameter list will
not be visible outside of this definition or declaration"

Fix this warning by including 'linux/dma-direction.h'.

Fixes: 6ff265fc5ef6 ("scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsg")
