Add fixup_dev_quirk vops in QCOM UFS platforms and provide an initial
vendor-specific device quirk table to add UFS device specific quirks
which are enabled only for specified UFS devices.

- Add DELAY_BEFORE_LPM quirk for Skhynix UFS devices to introduce a
  delay before VCC is powered off in QCOM platforms.
- Add DELAY_AFTER_LPM quirk for Toshiba UFS devices to introduce a
  delay after the VCC power rail is turned off in QCOM platforms.
- Move UFS_DEVICE_QUIRK_HOST_PA_TACTIVATE quirk from
  ufs_qcom_apply_dev_quirks to ufs_qcom_dev_fixups.

Signed-off-by: Manish Pandey <quic_mapa@quicinc.com>

Changes from v2:
- Addressed Mani's comments.
- Moved quirk for WDC to ufs_qcom_dev_fixups.

Changes from v2:
- Integrated Bart’s feedback and consolidated the patches into one.

I'd still like to have these quirks in the core driver if they apply to other
platforms as well. But I'll leave it up to you to check with respective device
manufacturers.
