scsi: ufs: Customize flush threshold for WriteBooster
Allow flush threshold for WriteBooster to be customizable by vendors. To
achieve this, make the value a variable in struct ufs_hba_variant_params.
Also introduce UFS_WB_BUF_REMAIN_PERCENT() macro to provide a more flexible
way to specify WriteBooster available buffer values.
