staging: sm750fb: Remove unused function sm750_enable_dma

Browse Source 
The function sm750_enable_dma is defined in ddk750_power.c and declared
in ddk750_power.h, but it is not called anywhere in the driver.

Remove the unused definition and declaration.

This addresses the first task in the drivers/staging/sm750fb/TODO list:
"- refine the code and remove unused code".
