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.
