MIPS: RB532: remove useless CF GPIO initialisation
As the pata-rb532-cf driver calls gpio_direction_input(), the calls to rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since the alternate function is automatically being disabled when changing the GPIO pin direction. The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being done by the IRQ initialisation of pata-rb532-cf.
