pci-arbiter: Stop using deprecated region memory pointer

Use a internal array of pointers instead

* pci-arbiter/device_map.h:
  * Update device_map_region() prototype
    * Now it receives an output address as parameter
* pci-arbiter/device_map.c:
  * Update device_map_region() definition to match the new prototype
  * Support for legacy mappings
    * When the base address is lower than 1 mb
* pci-arbiter/func_files.c:
* pci-arbiter/netfs_impl.c:
  * Update calls to device_map_region to match the new prototype
  * Use the internal array of pointers instead of region->memory
* pci-arbiter/pcifs.h:
  * struct pcifs_dirent: Declare the internal array of pointers
