This fixes a potential race condition where the ci13xxx_imx glue code
could be fast enough to call one of the usbmisc_ops before he got a
valid value on the static usbmisc pointer. To fix that we first set
usbmisc, then call usbmisc_set_ops().

The probe function checks usbmisc to be NULL in the beginning. Without
this patch the can only be loaded once.

This driver will be used for every Freescale SoC which has this misc
memory layout to control the basic usb handling. So better name this
driver, function and struct names in a more generic way.
