usb: add CONFIG_USB_OHCI_HCD in Kconfig

Browse Source 
Add this option as a common config for all OHCI controllers.  Its
help message was copied from Linux.  Also, I moved it below EHCI
to respect the order in Linux's Kconfig.

Add CONFIG_USB_OHCI_HCD=y to axs103_defconfig, which is the only
user of OHCI_GENERIC.

The Open Host Controller Interface (OHCI) is a standard for accessing
USB 1.1 host controller hardware. It does more in hardware than Intel's
UHCI specification. If your USB host controller follows the OHCI spec,
say Y. On most non-x86 systems, and on x86 hardware that's not using a
USB controller from Intel or VIA, this is appropriate. If your host
controller doesn't use PCI, this is probably appropriate. For a PCI
based system where you're not sure, the "lspci -v" entry will list the
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
