Warnings were generated because of the following commit changed data type for
address pointer
195bbca ARM: 7500/1: io: avoid writeback addressing modes for __raw_ accessors
add __iomem annotation to fix following warnings
drivers/media/platform/davinci/vpbe_osd.c: In function ‘osd_read’:
drivers/media/platform/davinci/vpbe_osd.c:49:2: warning: passing
argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [enabled by default]
arch/arm/include/asm/io.h:104:19: note: expected ‘const volatile
void *’ but argument is of type ‘long unsigned int’

Changes for v2:
1: Made the base addr to void __iomem * instead of long unsigned,
as pointed by Laurent.
