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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

+ 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.
