MFC r274670, r274671, r276168:
Moves all the duplicate code to a single function.
Verify for invalid modes and unwanted flags before pass the new flags to driver.
Make gpio_default_map_gpios() static. No functional changes.
Improves the GPIO API description a little bit.
gpio_pin_max must return the maximum supported pin number and not the total number of pins on the system.

MFC r273799:
Make the GPIO children attach to the first unit available and not only to unit 0.
This fix a bug where a GPIO controller could fail to attach its children (gpioc and gpiobus) if another GPIO driver attach first.

Fix undefined behaviour in several gpio_pin_setflags() routines (under sys/arm and sys/mips), squelching the clang 3.3 warnings about this.

The GPIO drivers were initialising their mutexes with type of MTX_NETWORK_LOCK. This is wrong since these mutexes have nothing to do with networking.

Allow for a default GPIO pin "high", which is required for some boards which tie the USB device enable to a GPIO line.

Remove these locks - they aren't strictly needed and cause measurable performance issues.
* Access to the GPIO bus is already locked by requesting and releasing the bus - thus the lock isn't really needed for each GPIO pin change. * Don't lock and unlock the GPIO bus for -each- i2c access - the i2c bus code is already doing this by calling the upper layer callback to request/release the bus. This thus locks the bus for the entirety of the transaction.
TODO:
* Further verify that everything is correctly requesting/ releasing the GPIO bus. * Look at how to lock the GPIO pin configuration stuff, potentially by locking/unlocking the bus at the gpiobus layer.

Re-jiggle the GPIO code a little to remove the hard-coded AR71xx GPIO config and function mask setup.
* "gpiomask" now specifies which GPIO pins to enable, for devices to bind to. * "function_set" allows bits in the function register to be set at GPIO setup. * "function_clear" allows bits in the function register to be cleared at GPIO setup.
The function_set/function_clear bits allow for individual GPIO pins to either drive a GPIO line or an alternate function - eg USB, JTAG, etc. This allows for things like CS1/CS2 be enabled for those boards w/ >1 SPI device connected, or disabling JTAG for the AR7240 (which is apparently needed ..)
I've verified this on the AR71xx.
