[PATCH] gpiolib: Switch order of valid mask and hw init

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

The GPIO irqchip needs to initialize the valid mask
before initializing the IRQ hardware, because sometimes
the latter require the former to be executed first.

Thinking of applying this for fixes to fix some part
of the problems that Hans is seeing.
