Hello,

This patch series adds UFS M-PHY and UFS host driver support in MediaTek chipsets.

In the meantime, re-factors ufshcd_get_pwr_dev_param in vendors' drivers. This function is for vendors to decide finally agreed attributes for power mode change if vendors define
their host capability in struct ufs_dev_params. Because it is using by both ufs-qcom and ufs-hisi and also used in ufs-mediatek in this serious, simply re-factor it and then every vendors can reuse it.

Changes since v1:
- Re-factor ufshcd_get_pwr_dev_param in mediatek/qcom/hisi vendor drivers.
- Introduce ufs-phy-mtk to have a good extension capability for different power control flows in future different MPHY versions.
- Bind ufs-phy-mtk and hook suitable callbacks in ufs-mediatek driver.
- Use PA_LOCAL_TX_LCC_ENABLE attribute defined in unipro.h instead.
- Do some minor format fixes.
