[PATCH v3 0/9] Add support for MediaTek xHCI host controller

[Chunfeng Yun]

The series of patches are used to support xHCI host controller on
MediaTek SoCs which has a glue layer IPPC (IP Port Control), and
add USB function on T-PHY including T-PHY V1 and V2;
Finally add USB related nodes for MT7629 platform.

The files of xhci-mtk.* and phy-mtk-tphy.* are ported from
Linux Kenrel 5.6-rc1

v3 changes:
    1. provide non/inline edev_get_child_count() suggested by Simon
    2. squash [PATCH v2 02/10] into [PATCH v2 03/10] suggested by Simon
    3. use macros to access IPPC registers suggested by Marek

v2 changes:
    1. move ofnode_get_child_count() into ofnode.c suggested by Simon
    2. add a test item for ofnode_get_child_count() suggested by Simon
    3. use clk_bulk to get clocks suggested by Marek
    4. use clrsetbits_le32() etc suggeseted by Marek
    5. get the count of phys by dev_get_child_count()
    6. drop reference to fixed clock clk20m
