3f9b6cec12 scsi: ufs: ufs-mediatek: Introduce workaround for power mode change
Some MediaTek SoC chips need special flow for power mode change, especially
for chips supporting HS-G5.

Enable the workaround by setting the host-specific capability.

cb2bf7c6e5 scsi: ufs: host: ufs-exynos: Use already existing definition
UFS core already uses RX_MIN_ACTIVATETIME_CAPABILITY macro, let's use the
same in driver as well instead of having a different macro name for the
same offset.

dd11376b9f 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.
