staging: sm750fb: Remove unused return variable in program_mode_registers()

Browse Source 
Drops variable ret as it is unused in the code. This therefore modifies
the return type of program_mode_registers() to void from int since the
return value is being ignored in all function calls. This improves code
readability and maintainability.
