[XEN v1 3/9] xen/arm: Always use 'u64' instead of 'paddr_t' for address and size in DT

[Ayan Kumar Halder]

device_tree_get_reg(), dt_next_cell() uses u64 for address and size.
Thus, the caller needs to be fixed to pass u64 values and then invoke
translate_dt_address_size() to do the translation between u64 and paddr_t.
