[PATCH 00/11] MT8195: add ufs support

[Julien Stephan]

This series adds ufs support MT8195.
I also include in this series some cleanup on phy-mtk-ufs.c phy driver
and ufs-mediatek.c mediatek ufs driver, and pmic support for MT8195.

UFS boot has been tested on a MT8395_EVK board.
To enable ufs boot, we first need to erase mmc partitions.

The configs in config mt8395_evk_ufs are the minimum configs needed to
enable UFS. This has been validating with the following commands on
u-boot (extra configs needed for non generic configuration):
