[Po-Wen Kao <powen.kao@mediatek.com>]

v4 -> v5
- Remove unused define in header
- Let chatty log print only at debug level
- Correct ufs_mtk_init_mcq_irq() that was wrongly fixed

v3 -> v4
Address AngeloGioacchino's comments.

v2 -> v3
- Drop SQ to CQ mapping vops introduced in v2
- Refactor commit message
- Update export symbols

v1 -> v2
- Introduce MCQ SQ to CQ mapping vops and provide MTK implementation.
- Update export symbol patch

v1
- Separated from topic "[PATCH v4 0/5] Several UFS MCQ Code Changes".
  Here are some changes since last upload
  - Store irq in per host array
  - Symbol rename
  - Use ufshcd_mcq_poll_cqe_lock() instead of ufshcd_mcq_poll_cqe_nolock()
  - Handle invalid irq dts property
  - Remove ufshcd_disable_intr(hba, MCQ_CQ_EVENT_STATUS) in MCQ mode.
    This will become host quirk later.
