powerpc/QE: prepare QE PIO code for GPIO LIB support
- split and export __par_io_config_pin() out of par_io_config_pin(), so we
could use the prefixed version with GPIO LIB API;
- rename struct port_regs to qe_pio_regs, and place it into qe.h;
- rename #define NUM_OF_PINS to QE_PIO_PINS, and place it into qe.h.
