USB: ohci: allow platform driver to specify the number of ports

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

This patch modifies the ohci platform driver to accept the num_ports
parameter to be set via platform_data. Setting the number of ports must be
done after the call to ohci_hcd_init().
