[v3,0/2] scsi: ufs: pass device information to apply_dev_quirks

Currently UFS driver has "global" device quirk scheme to allow driver applying
special handling for certain UFS devive models.

However some special device handlings are required for specific UFS hosts only
so it is better to make it happen in vendor's callbacks only to not "pollute"
common driver and common device quirks.

We already have apply_dev_quirks variant callback for vendors but lack of device
information for handling specific UFS device models. This series provides such
information to apply_dev_quirks callbacks, and applies related modifications.

In patch 1, since QCOM vendor driver will be built by default as a module, UFS
core driver and vendor driver can not be split to different patches, otherwise
separated patches will not be built singly.

v2 -> v3
    - Fix ufshcd_tune_unipro_params()'s users to have correct parameters for invoking.
    - Rebase to Martin's latest queue branch.

v1 -> v2
    - Squash patch 1 "scsi: ufs: pass device information to apply_dev_quirks" and patch 2 "scsi: ufs-qcom: modify apply_dev_quirks interface" to resolve build issue.

Applied to 5.6/scsi-queue, thanks!
