The RealView PBX board has two 512MB blocks of memory - one at
0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the
block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g.
framebuffer). This patch adds the sparsemem definitions to allow the use
of all the memory split as follows:

  256MB @ 0x00000000 (ZONE_DMA)
  512MB @ 0x20000000 (ZONE_NORMAL)
  256MB @ 0x80000000 (ZONE_NORMAL)

This moves the mmci platform data definition struct away from
arch/arm/include/asm/mach/mmc.h into the more proper place among
the other primecells in include/linux/amba/mmci.h and at the same
time renames it to "mmci.h", and also the struct in this file
confusingly named mmc_platform_data has been renamed
mmci_platform_data for clarity.

either referring to the base address of corresponding versatile

the device identifier as a string. I kept the "dev:" prefix for
DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the
other processor bus, just in case someone likes them.

This patch adds dummy local timers for each CPU so that the board clock
device is used to broadcast events to the other CPUs. The patch also
adds the declaration for the dummy_timer_setup function (the equivalent
of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).

Due to the way clockevents work, the dummy timer on the first CPU has to
be registered before the board timer.
