[PATCH v3 03/18] ARM: clps711x: Transform clps711x-framebuffer to platform driver and use it

[shc_work@mail.ru (Alexander Shiyan)]

clps711x-framebuffer driver needs to be updated and this is a first step
to make driver better. With this patch we are convert clps711x-framebuffer
to platform device and load this driver from board code.
