ARM: OMAP1: OHCI: use platform_data fn ptr to enable OCPI bus
The OMAP1 OHCI driver needs to enable the OCPI IP block before it can work. Previously, the driver was simply calling a symbol defined in the OMAP platform code, but this is incorrect: drivers should be fully decoupled from platform and architecture code. So instead, modify the driver to call through a platform_data function pointer instead. We skip any DT aspect, since OMAP1 is not scheduled to be converted to DT in the near future. This resolves the following sparse warning: It also gets rid of a cpu_is_omap16xx() call in a driver. In the long term, it probably makes sense to move the OCPI bus code to somewhere under drivers/. This should avoid the whole platform_data/DT issue with this function.
