Hi,

the series is adding basic support for this USB hub. The key part is
running reset over GPIO line and when i2c is connected it is necessary to
send command to boot the hub. This chip is available on Xilinx
zcu100/Ultra96 v1 board.

Thanks,
Michal

Changes in v2:
- s/USB_USB5744/USB_HUB_USB5744/g
- Fix order in Makefile and Kconfig
