This converts the ARM RealView machine over to using the common
clock. The approach is similar to the one used for the Integrator,
and we're reusing the ICST wrapper code.

We have to put the clock intialization in the timer init function
for the clocks to be available when initializing the timer,
keeping them in early_init() is too early for the common clk.

Since we now have to go down and compile drivers/clk/versatile
a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper
code gets compiled into the kernel for either machine. A leftover
CLK_VERSATILE in the Integrator Kconfig was fixed up to use
the new symbol as well.

Tested on ARM RealView PB1176.

The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.

This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

This replaces the custom LED trigger code in mach-realview with
some overarching platform code for the plat-versatile family that
will lock down LEDs 2 thru 5 for CPU activity indication. The
day we have 8 core ARM systems the plat-versatile code will have
to become more elaborate.

Tested on RealView PB11MPCore by invoking four different CPU
hogs (yes > /dev/null&) and see the LEDs go on one at a time.
They all go off as the hogs are killed. Tested on the PB1176
as well - just one activity led (led 2) goes on and off with
CPU activity.

Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an
AMBA device is registered with this parameter. With the pending NO_IRQ
cleanup, this will lead to a warning at boot time, since -1 is obviously
broken.

This patch updates the interrupt used for GPIO0 to match that specified
by the TRM. Unfortunately, it's not clear how to trigger this interrupt
so we trust that the documentation is correct.

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.
