If we are the console then a printk can hit us with a spin lock held (and
in fact the kernel will do its best to take printing lock).

In that case we cannot politely sleep when synching after an accelerated op
but must behave obnixously to be sure of getting the bits out.

Tegra doesn't have irq_to_gpio() any more, and ak8975 is included in
tegra_defconfig. This causes a build failure. Instead, pass the GPIO name
through platform data.

to remove the irq_to_gpio() call]
