net: allwinner: Fix print format

Kees reports quoted commit introduced the following warning on arm64:

drivers/net/ethernet/allwinner/sun4i-emac.c:922:60: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'resource_size_t' {aka 'long long unsigned int'} [-Werror=format=]

      |                                                           ~^
      |                                                            |                                      |                                                            unsigned int
      |                                                           %llx
  923 |                     regs->start, resource_size(regs));
      |                     ~~~~~~~~~~~

      |                         resource_size_t {aka long long unsigned int}

.. and another one like that for resource_size().

Switch to %pa and a cast.
