of: unittest: Fix build on architectures without CONFIG_OF_ADDRESS 

commit aed5041ef9 upstream.

of_dma_get_max_cpu_address() is not defined if !CONFIG_OF_ADDRESS, so
return early in of_unittest_dma_get_max_cpu_address().

Fixes: 07d13a1d61 ("of: unittest: Add test for of_dma_get_max_cpu_address()")
