[PATCH v4 0/7] Add the USB5744 hub driver as per new DT binding

[Venkatesh Yadav Abbarapu]

Add the usb5744/usb2744 hub driver which does the reset gpio toggling
and the i2c initialization sequence.

Tested the USB5744/USB2744 usb hub for usb0, usb1 with the
DT nodes on KR260 board.

Changes in v2:
- Added the power_on_reset_us variable, for post-reset time.
- Removed the DM_REGULATOR ifdef around the regulator API's.
- Rename the i2c_init and fixed the return for the API's.

Changes in v3:
- Rename i2c_init to init.
- Fixed the return values for the dev_read_phandle_with_args API.
- Removed the unneccessary cast uint8_t *.

Changes in v4:
- Fixed the indentation issues.
- Fixed the Reverse xmas tree for indentation.
- Replaced dev_dbg to dev_err in all places.
