CVS commit: src/sys/dev/gpio

Modified Files:
        src/sys/dev/gpio: gpio.c

Log Message:
Bug fix: record the new state (high/low) set by gpio_pin_write().
I don't know why we gpio(4) didn't do that before, but it seems
harmless.

Add naive power handling: when a gpio(4) instance is resumed, write
each pin's configuration flags and output state from the softc to
the hardware using gpiobus_pin_ctl() and gpiobus_pin_write().
While suspended, fail every ioctl() except for GPIOINFO with EBUSY.
