Hi,

This patchset applies some driver cleanups and performance improvement
in ufs host drivers by making the delay for host enabling customizable
according to vendors' requirements.

v3 -> v4
- Collect review tags in v2
- In patch #8, fix incorrect condition of customized delay for host enabling

v2 -> v3
- Remove /arch/arm64/configs/defconfig chnage because it is for local test only

v1 -> v2
- Add patch #1 "scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc"
- Remove struct ufs_init_prefetch in patch #2 "scsi: ufs: remove init_prefetch_data in struct ufs_hba"
- Introduce common delay function in patch #4
- Replace all delay places by common delay function in ufs-mediatek in patch #5
- Use common delay function instead for host enabling delay in patch #6
- Add patch #7 "scsi: ufs: make HCE polling more compact to improve initializatoin latency"
- In patch #8, customize the delay in ufs_mtk_hce_enable_notify callback instead of ufs_mtk_init (Avri)
