drm: xlnx: mixer: Fix linking failure for ARCH arm

The kernel fails to build on 32-bit arm architecture when Video Mixer
driver is enabled due to unsupported modulo operations in 32 bit mode.
The error shown is "undefined reference to `__aeabi_uldivmod'".
This is fixed by changing the data type of luma and chroma address to
dma_addr_t instead of u64.
