[3/3] drivers/video/s3c2410fb.c: Convert release_resource to release_mem_region

Commit Message

Request_mem_region should be used with release_mem_region, not
release_resource.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@s exists@
expression e1,e2,e3,e4,e;
@@

*e4 = request_mem_region(e1,e2,e3)
... when != e4 = e
*release_resource(e4);
// </smpl>
