Everything required to populate NVIDIA Tegra devices from the device
tree.  This patch adds a new DT_MACHINE_DESC() which matches against
a tegra20 device tree.  So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.

Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

Now most of ARM machines has the alsmot same __clk_get/put() macro

So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files

But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config

Now there are only 3 caese.

1) define the clk structure with clkdev macro => Need to move clk structure to proper header file

arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h

2) export the __clk_get/put function at clock.c

arch/arm/mach-shmobile/include/mach/clkdev.h

3) demuxing the clk source

Ensure the built-in eMMC is always named mmcblk0.

This is important because:

* U-Boot statically assigns MMC device IDs based on controller ID.
* U-Boot assumes that kernel MMC device ID numbering matches U-Boot numbering.
* U-Boot provides a kernel cmdline option e.g. root=/dev/mmcblk0p3 based on
  that numbering.
* The kernel dynamically assigns MMC device IDs based on enumeration order of
  the memory behind the host controller, rather than statically based on host
  controller ID like U-Boot.
* By registering the SDHCI controller for the built-in eMMC first, the
  enumeration of the built-in eMMC is performed first, and hence eMMC gets
  assigned ID 0 just like U-Boot. If the SD slot is filled, it then gets
  assigned ID 1 just like U-Boot.
* If the MMC IDs mismatch, and the system boots from SD card not eMMC, the
  kernel will access the eMMC instead of SD card when attempting to mount
  /dev/mmcblk1p3 as the root fs. If eMMC is not partitioned/formatted, the
  kernel will panic since the root fs can't be mounted. If eMMC is partitioned
  and formatted, the kernel will mount an unexpected filesystem as the root fs.

This change relies on the SDHCI driver performing initial card detection
synchronously during device registration. This is currently the case.

If an ARM system has multiple cpus in the same socket and the
kernel is booted with maxcpus=1, secondary cpus are possible but
not present due to how platform_smp_prepare_cpus() is called.
Since most typical ARM processors don't actually support physical
hotplug, initialize the present map to be equal to the possible
map in generic ARM SMP code. Also, always call
platform_smp_prepare_cpus() as long as max_cpus is non-zero (0
means no SMP) to allow platform code to do any SMP setup.

After applying this patch it's possible to boot an ARM system
with maxcpus=1 on the command line and then hotplug in secondary
cpus via sysfs. This is more in line with how x86 does things.

Currently, both the WM8903 and TPS6586x chips attempt to register with

board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.
