drm: use c99 initializers in structures

Author: Julia Lawall <Julia.Lawall@lip6.fr>

Use c99 initializers for structures.

Drop 0 initializers in drivers/gpu/drm/sti/sti_vtac.c.  A 0x0 initializer
is left in vtac_mode_aux in drivers/gpu/drm/sti/sti_vtac.c to highlight the
relation to vtac_mode_main.

A simplified version of the semantic match that finds the first problem is
as follows: (http://coccinelle.lip6.fr/)

// 
@decl@
identifier i1,fld;
type T;
field list[n] fs;
@@

struct i1 {
 fs
 T fld;
 ...};

@bad@
identifier decl.i1,i2;
expression e;
initializer list[decl.n] is;
@@

struct i1 i2 = { is,
+ .fld = e
- e
 ,...};
// 

v2: Drop 0 initializers and add trailing commas at the suggestions of Josh
Triplett.
