[PATCH] staging: sm750fb: fix checkpatch warning architecture specific defines should be avoided

[Michael Anckaert]

Replace architecture-specific defines with CONFIG_X86 checks to improve
portability and adhere to kernel coding standards.

Fixes checkpatch warning:
- CHECK: architecture specific defines should be avoided.

Changes made:
- Using CONFIG_X86 instead of i386 and x86.

Maybe move the '} else {' into the ifdef to avoid the possibly empty 
else branch. I also wonder why this is only being done on x86. There are 
other systems with VGA.

In any case
