Title: Make st7735fb work

1. Prevent bcm2708 binding spidev to SPI CS0.
2. Add module to bind SPI CS0 to ST7735FB instead (CONFIG_FB_ST7735_MAP).
3. Move st7735fb driver to separate folder to allow loading after SPI if driver is built-in to kernel.

Can now be built either as two modules or built-in to kernel. NOTE: if built-in, you still cannot use it with fbcon as it appears the fbcon is incompatible with SPI and/or deferred I/O framebuffers.

If built as modules, run:

# modprobe st7735fb
# modprobe st7735fb_map

You should then get /dev/fb1.
