[PATCH] drivers/video/fbdev/fb-puv3.c: Add header files for function unifb_mmap

[sunzc522]

From: Zhichuang SUN <sunzc522@xxxxxxxxx>

Function unifb_mmap calls functions which are defined in linux/mm.h
and asm/pgtable.h

The related error (for unicore32 with unicore32_defconfig):
	CC      drivers/video/fbdev/fb-puv3.o
	drivers/video/fbdev/fb-puv3.c: In function 'unifb_mmap':
	drivers/video/fbdev/fb-puv3.c:646: error: implicit declaration of
				      function 'vm_iomap_memory'
	drivers/video/fbdev/fb-puv3.c:646: error: implicit declaration of
				      function 'pgprot_noncached'
