JZ4740: Add SLCD support

This patch series adds SLCD support to the Jz4740 framebuffer driver and adds a LCD panel driver for the Truly G240400RTSW using the newly-exported SLCD data transmission functions.

I'm not sure about the way I've handled this (jz4740_fb_slcd_*), so I marked the relevant patches as RFC. This could be done by emulating SPI, but as this seemed too much work for little benefit I picked the lazy way out.

Maurus Cuelenaere (6):
FBDEV: JZ4740: Refactor GPIO pin operations
FBDEV: JZ4740: Initialize jzfb->fb earlier
FBDEV: JZ4740: Initialize framebuffer properly
FBDEV: JZ4740: Add Smart LCD controller support
FBDEV: JZ4740: Get rid of enumeration value not handled in switch
warnings
