mm: print physical addresses consistently with other parts of kernel
Print physical address info in a style consistent with the %pR style used
elsewhere in the kernel. For example:
-Zone PFN ranges:
+Zone ranges:
- DMA32 0x00000010 -> 0x00100000
+ DMA32 [mem 0x00010000-0xffffffff]
- Normal 0x00100000 -> 0x01080000
+ Normal [mem 0x100000000-0x107fffffff]
