[v6,00/11] Combine the two UFS driver scsi_add_host() calls

Hi Martin,

In the UFS driver the legacy and MCQ scsi_add_host() calls occur in different
functions. This patch series reduces the number of scsi_add_host() calls from
two to one and hence makes the UFS driver easier to maintain.

Please consider this patch series for the next merge window.

Thanks,

Bart.

Changes compared to v5:
 - Rebased this patch series on top of the v6.12-rc kernel.
 - Removed the probe_start member variable again from struct ufs_hba.
 - Renamed ufshcd_process_device_init_result() into
   ufshcd_process_probe_result().
 - Converted a comment about UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH into an
   explicit test.

Changes compared to v4:
 - Left out the changes that remove the 'init_dev_params' argument.
 - Added a few new patches.

Changes compared to v3:
 - Split patch "Move the MCQ scsi_add_host() call" into two patches to make
   it easier for reviewers.

Changes compared to v2:
 - Improved several patch descriptions.
 - Moved one source code comment.

Changes compared to v1:
 - Fixed a compiler warning reported by the kernel build robot.
 - Improved patch descriptions.
