net: dlink: enable RMON MMIO access on supported devices
Enable memory-mapped I/O access to RMON statistics registers for devices
known to work correctly. Currently, only the D-Link DGE-550T (`0x4000`)
with PCI revision A3 (`0x0c`) is allowed.
To avoid issues on other hardware, a runtime check was added to restrict
MMIO usage. The `MEM_MAPPING` macro was removed in favor of runtime
detection.
To access RMON registers, the code `dw32(RmonStatMask, 0x0007ffff);`
must also be skipped, so this patch conditionally disables it as well.
Tested-on: D-Link DGE-550T Rev-A3
