[rtl818x] Remove broken mmio register support

The rtl818x driver uses programmed I/O but has a fallback to memory-mapped I/O registers. The fallback currently will not work since the registers are accessed using inl()/outl() programmed I/O functions in the driver. This patch removes the fallback to we fail cleanly when programmed I/O is not possible.
