Structure ufs_dev_params is actually used in UFS host drivers to declare
host specific power mode parameters, like ufs_<vendor>_params or host_cap,
which makes the code not very straightforward to read. Rename the structure
ufs_dev_params to ufs_host_params and unify the declarations in all drivers
to host_params.
In addition, rename the two functions ufshcd_init_pwr_dev_param() and
ufshcd_get_pwr_dev_param() which work based on the ufs_host_params to
ufshcd_init_host_params() and ufshcd_negotiate_pwr_params() respectively to
avoid confusions.
This change does not change any functionalities or logic.

Bindings do not allow vdd-hba-max-microamp property and the driver does not
use it (does not control load of vdd-hba supply). Skip looking for this
property to avoid misleading dmesg messages:
ufshcd-qcom 1d84000.ufs: ufshcd_populate_vreg: unable to find vdd-hba-max-microamp

All UFS host drivers call ufshcd_shutdown(). Hence, instead of calling
ufshcd_shutdown() from the host driver .shutdown() callback, inline that
function into ufshcd_wl_shutdown().

Export below regulator functions to allow vendors to
customize regulator configuration in their own platforms.

struct ufs_vreg **out_vreg);

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.
