Currently only one USB port on mx5 boards can be enabled and that
USB port is defined by CONFIG_MXC_USB_PORT.  Removing the use of
CONFIG_MXC_USB_PORT and instead supporting
CONFIG_USB_MAX_CONTROLLER_COUNT to populate that number of USB ports
starting with port 0 allows multiple USB ports to be used.

Examples:
If port 0 and port 1 are populated, the value of
 CONFIG_USB_MAX_CONTROLLER_COUNT should be set to 2 and both port 0
and port 1 are initialized.

If only port 1 is populated, the value of
CONFIG_USB_MAX_CONTROLLER_COUNT should be set to 2 and port 0 and
port 1 are initialized, but port 0 is not used.

If only port 0 is populated, the value of
CONFIG_USB_MAX_CONTROLLER_COUNT should be set to 1 and port 0 is
the only USB port initialized.
