usb: add CONFIG_USB_OHCI_HCD in Kconfig

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.
