s3c2410fb: fix sections

Since the drivers probe calls were changed from .init.text to
.devinit.text in commit c2e13037
("platform-drivers: move probe to .devinit.text in drivers/video") all the
function from .init.text should be moved to .devinit.text, too.

The drivers remove calls can also be move from .text to .devexit.text.
