ARM: OMAP: Remove broken LCD driver for SX1 



Recently the omap McBSP code was cleaned up to get rid of
direct McBSP register tinkering by the drivers. Looks like
lcd_sx1.c never got converted, and now it breaks builds.

It seems the lcd_sx1.c driver is attempting SPI mode, but
doing it in a different way compared to omap_mcbsp_set_spi_mode().

Remove the broken driver, patches welcome to add it back when
done properly by patching both mcbsp.c and lcd_sx1.c.
