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.

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
	- 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)
