[PATCH v2 0/9] 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):

Changes in v2:
- Add dependency on [1] that rename the genio defconfig
- rename mt8395_evk_ufs_defconfig to the new name
  mt8395_genio_1200_evk_ufs_defconfig
- introduce mt8195.config to avoid duplicating mt8395_genio_1200_evk defconfig
- Added new reviewed-by by tag
- add missing clk_enable in ufs driver and fix error path
- remove pmic commits from this series. As suggested by David, this
  driver need some rework and deserve it's own series. UFS still
  works, since previous bootloader stage is already doing some
  initialization
