[PATCH v3 0/3] scsi: ufs: core: support WB buffer resize function

[Lu Hongfei <luhongfei@vivo.com>]

Hello,

In August 2023, the ballot for resizing the WriteBooster buffer has been
approved.

This v3 series implements the function of controlling the WriteBooster
buffer resize via sysfs that will be supported in UFS.

version 2 changes
-Using sysfs to control WB buffer resize instead of exception event handler
-Removed content related to exception event
-Solved several issues that caused compilation errors

version 3 changes
-Removed UFS version number check
-Optimized several function names to make their definitions clear and easy
to understand
-Fixed several formatting issues to avoid reporting warning information
during compilation
-Removed the ufshcd_scsi_block_requests(), ufshcd_wait_for_doorbell_clr()
and ufshcd_scsi_unblock_requests() calls in ufshcd_configure_wb_buf_resize.
