This adds the callback for set_multiple.
As this controller has a separate set and clear register, we can't write
directly to PIO_ODSR as this would required a cached variable and would
race with at91_gpio_set.
So build masks for the PIO_SODR and PIO_CODR registers and write them
together.

This was tested by using an own test driver which uses
gpiod_set_array_cansleep to set multiple GPIOs at once.

I remember J-C brought this up ages ago, so I hope he will be delighted
to see we can now, FINALLY, do this!

J-C can I have your review on this?
