MIPS: SEAD3: Drop use of cobalt fbdev driver
The 2 line * 16 character LCD display on the SEAD3 board has no real use as a framebuffer device. It's far too small to produce any meaningful output if used as the kernel console, SEAD3 is a development board that will essentially always have a far more useful UART connection & the code in sead3-display.c will overwrite whatever's on the display every second anyway. Remove this unused code.
