Staging: sm750fb: provide error path for hw_sm750le_setBLANK()
This provides a default path for the switch statement in hw_sm750le_setBLANK() so that the compiler will not correctly complain about undefined values being sent to the hardware. Instead, properly error out if the blank command is unknown by the driver.
