scsi: ufs: Split the drivers/scsi/ufs directory

Split the drivers/scsi/ufs directory into 'core' and 'host' directories
under the drivers/ufs/ directory. Move shared header files into the
include/ufs/ directory. This separation makes it clear which header files
UFS drivers are allowed to include (include/ufs/*.h) and which header files
UFS drivers are not allowed to include (drivers/ufs/core/*.h).

Update the MAINTAINERS file. Add myself as a UFS reviewer.

-	  UFS Protocol Information Units (UPIUs).
-	  UPIUs can not only be used as a transport layer for the SCSI protocol
-	  but are also used by the UFS native command set.
-	  This transport driver supports exchanging UFS protocol information units
-	  with a UFS device. See also the ufshcd driver, which is a SCSI driver
-	  that supports UFS devices.
