This patch fixes two problems with the error handling in the
grvga_probe function and simplifies it making the code
easier to read.
- If the call to grvga_parse_custom on line 370 fails we use
the wrong label so that release_mem_region will be called
without a call to request_mem_region being made.
- If the call to ioremap on line 436 fails we should not try
to call iounmap in the error handling code.
This patch introduces the following changes:
- Converts request_mem_region into its devm_ equivalent
which simplifies the otherwise messy clean up code.
- Changes the labels for correct error handling and their
names to make the code easier to read.

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.
