[PATCH 2/2] staging: sm750fb: Remove unused return value in program_mode_registers()

[Dorcas AnonoLitunya <anonolitunya@gmail.com>]

Modifies the return type of program_mode_registers()
to void from int as the return value is being ignored in
all subsequent function calls.

This improves code readability and maintainability.
