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

[Riyan Dhiman]

Abstract out x86-specific code in ddk750_init_hw() to improve
portability and adhere to kernel coding standards. Replaces
architecture-specific defines with CONFIG_X86 checks.

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

Changes made:
- Create a new function sm750le_set_graphic_mode to encapsulate architecture
specifc behaviour.
- Using CONFIG_X86 instead of i386 and x86.
- Added placeholder for non-x86 architectures in sm750le_set_graphic_mode
function.
