unicore32 machine related: add frame buffer driver for pkunity-v3 soc
change from original version -- by advice of Paul Mundt 1. remove videomemorysize definitions 2. remove unifb_enable and unifb_setup 3. use dev_warn instead of printk in fb driver 4. remove judgement for FB_ACCEL_PUV3_UNIGFX 5. adjust clk_get and clk_set_rate calls 6. add resources definitions 7. remove unifb_option 8. adjust register for platform_device 9. adjust unifb_ops position and unifb_regs assignment position Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Acked-by: Arnd Bergmann <arnd@arndb.de>
