OMAP: RX51: Add Touch Controller in SPI board info

Browse Source 
The Touch controller and LCD Panel share the same SPI bus 1.
So, we need to define the touch controller in the SPI board info
else, the SPI bus will be contended due to invalid state of
Touch controller's Chip Select thus preventing the LCD panel
from working.
