grvga: fix section mismatch warnings

Fix following section mismatch warnings:

WARNING: drivers/video/built-in.o(.devinit.text+0x110): Section mismatch in reference from the function grvga_probe() to the function .init.text:grvga_parse_custom()
The function __devinit grvga_probe() references
a function __init grvga_parse_custom().
If grvga_parse_custom is only used by grvga_probe then
annotate grvga_parse_custom with a matching annotation.

WARNING: drivers/video/built-in.o(.devinit.text+0x1f8): Section mismatch in reference from the function grvga_probe() to the variable .init.data:grvga_fix
The function __devinit grvga_probe() references
a variable __initdata grvga_fix.
If grvga_fix is only used by grvga_probe then
annotate grvga_fix with a matching annotation.

WARNING: drivers/video/built-in.o(.devinit.text+0x204): Section mismatch in reference from the function grvga_probe() to the variable .init.data:grvga_fix
The function __devinit grvga_probe() references
a variable __initdata grvga_fix.
If grvga_fix is only used by grvga_probe then
annotate grvga_fix with a matching annotation.

grvga_fix is used in a function annotated __devinit - so
match this using a __devinitdata annotation on grvga_fix.

grvga_parse_custom() is used in a function annotated
__devinit - so match this by annotating grvga_parse_custom()
with __devinit too.
