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.
