lcd: add SPI-based LCD and backlight driver for SHARP corgi/spitz
The driver is based on different source files including corgi_ssp.c, corgi_lcd.c and corgi_bl.c, previously authored by Richard Purdie and many others. The LCD and Backlight device actually share the same SPI device, so they are made into this single driver.
