Pull up following revision(s) (requested by bouyer in ticket #1004):
        sys/arch/arm/allwinner/awin_gpio.c: revision 1.19
        sys/arch/arm/allwinner/awin_gpio.c: revision 1.20
Print the port name when gpio(4) attaches, makes it much easier to find
what port is connected to what gpio instance:
gpio0 at awingpio0: 18 pins
gpio0: port B
gpio1 at awingpio0: 25 pins
gpio1: port C
gpio2 at awingpio0: 28 pins
gpio2: port D
gpio3 at awingpio0: 12 pins
gpio3: port E
gpio4 at awingpio0: 12 pins
gpio4: port G
gpio5 at awingpio0: 28 pins
gpio5: port H
gpio6 at awingpio0: 22 pins
gpio6: port I
Based on suggestion from jared, redo previous using a specific print callback
to avoid the extra line. Now output looks like:
gpio0 at awingpio0 port B: 18 pins
gpio1 at awingpio0 port C: 25 pins
gpio2 at awingpio0 port D: 28 pins
gpio3 at awingpio0 port E: 12 pins
gpio4 at awingpio0 port G: 12 pins
gpio5 at awingpio0 port H: 28 pins
gpio6 at awingpio0 port I: 22 pins
