axs103: add support of generic OHCI USB 1.1 controller
This commit adds support of USB 1.1 storage media on AXS103 board.
For some yet unknown reason USB 2.0 doesn't work on AXS103 board issuing
messages like this:
------------------------>8-------------------
AXS# usb start
starting USB...
USB0: USB EHCI 1.00
scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80
unable to get device descriptor (error=-1)
1 USB Device(s) found
------------------------>8-------------------
As a work-around we're falling back to USB 1.1.
Indeed it is much slower but at least USB storage devices are usable on
AXS103.
