ARM: ks8695: __arch_virt_to_dma type handling
__arch_virt_to_dma expects a virtual address pointer, but
the ks8695 implementation of this macro treats it as an
integer. Adding a type cast avoids hundreds of identical
warning messages.
Without this patch, building acs5k_defconfig results in:
arch/arm/include/asm/dma-mapping.h: In function 'virt_to_dma':
arch/arm/include/asm/dma-mapping.h:60:2: warning: passing argument 1 of '__virt_to_phys' makes integer from pointer without a cast [enabled by default]
arch/arm/include/asm/memory.h:172:60: note: expected 'long unsigned int' but argument is of type 'void *'
