Gigabeat LCD driver cleanup: Revert the DMA optimisations to the gigabeat LCD driver - they are both buggy (the wrong background colour was often seen, e.g. in the USB screen after using a plugin) and significantly slower than the standard implementations (which use the ARM-optimised mem* functions) in lcd-16bit.c. lcd_clear_update was 4.5 times slower with DMA when a backdrop is in use, and 12 times slower with DMA when no backdrop is in use.
