USB: ohci: Add Kconfig entries for ohci-omap3

On OMAP systems, we have two different OHCI controllers. The legacy
one is present in OMAP1/2 chips, and the newer one comes bundled as
a companion to the EHCI controller on OMAP3 and newer chips.

We may have multi-omap configurations where OMAP2 and OMAP3
support may be enabled in the same kernel, and need a mechanism
to keep both drivers around.

This patch adds a Kconfig entry for each of these drivers.
