Hi all,
Here is v2 of the patchset.
This patchs for supporting WB of vendor specific.
- when UFS reset and restore, need to cleare WB buffer.
- need to check WB buffer and flush operate before enter suspend
- do not enable WB with UFS probe.

[v1 -> v2]
- The ufshcd_reset_vendor() fuction for WB reset.
So I modified function name.
- uploade vendor wb code.

  scsi: ufs: modify write booster
  scsi: ufs: modify function call name When ufs reset and restore, need
    to disable write booster
  scsi: ufs: add vendor specific write booster To support the fuction of
    writebooster by vendor. The WB behavior that the vendor wants is
    slightly different. But we have to support it
