drm/irq: Make pipe unsigned and name consistent
Name all references to the pipe number (CRTC index) consistently to make
it easier to distinguish which is a pipe number and which is a pointer
to struct drm_crtc.
While at it also make all references to the pipe number unsigned because
there is no longer any reason why it should ever be negative.
