drm: Reduce the amount of dev->vblank[crtc] in the code

Declare a local struct drm_vblank_crtc * and use that
instead of having to do dig it out via 'dev->vblank[crtc]'
everywhere.

Performed with the following coccinelle incantation,
and a few manual whitespace cleanups:

@@
identifier func,member;
expression num_crtcs;
struct drm_device *dev;
unsigned int crtc;
@@
func (...) {
+ struct drm_vblank_crtc *vblank;
...
if (crtc >= num_crtcs)
   return ...;
+ vblank = &dev->vblank[crtc];
<+...
(
- dev->vblank[crtc].member
+ vblank->member
|
- &(dev->vblank[crtc])
+ vblank
)
...+>
}

@@
struct drm_device *dev;
int crtc;
identifier member;
expression num_crtcs;
@@
for (crtc = 0; crtc < num_crtcs; crtc++) {
+ struct drm_vblank_crtc *vblank = &dev->vblank[crtc];
+
<+...
(
- dev->vblank[crtc].member
+ vblank->member
|
- &(dev->vblank[crtc])
+ vblank
)
...+>
}

func (struct drm_device *dev, int crtc, ...) {

<+...

- dev->vblank[crtc].member

|
- &(dev->vblank[crtc])
+ vblank
)
...+>
}
