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.
