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.
