ARM: 6204/1: Fixups for the RealView PB1176

This is a number of basic fixes to the PB1176 that makes it tick
properly:

- Detect MMC insertion/removal even when PL061 GPIO is not compiled
  in. The register to read this status directly is removed on the
  PB1176.
- Define the UART3 on the DevChip (where is actually is) and define
  the new UART4 serial port on the FPGA.
- Also define the clocks for these two UARTs apropriately.
- Remove the false notion that the PB1176 should have its CLCD
  on the ISSP, this is not the case, it is in the DevChip.
- Remove the defintions and the previously commented-out PL081
  DMAC. As confirmed by mail this was found to be broken on the
  PB1176 board and removed from the subsequent FPGA images.
