drm/nouveau/gpio: check function 76 in the power check as well
Added GPIO is "Power Alert". It's uncertain if this
GPIO is set on GPU initialization or only if a change is detected by the
GPU at runtime.
This GPIO can be found on Tesla and sometimes on Fermi GPUs.
Untested, wrote according to documentation.
