[PATCH 1/3] staging: sm750fb: Replace set_DAC macro with a static function

["Ali Köse" <shroot1337@gmail.com>]

Replace the set_DAC macro with a static function named set_dac().
The helper has only one caller, so keep it local to ddk750_display.c
and remove the macro from ddk750_power.h.

This provides parameter type checking and follows kernel naming
conventions without changing the register operation.
