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.
