ARM: tegra: multi-platform conversion

This branch converts Tegra to support multi-platform/single-zImage.

One header is made accessible to drivers. The earlyprintk implementation
is moved to the multi-platform location. Some Kconfig changes are made
to enable multi-platform. Some dead files are deleted.

The APIs exposed in the now-global tegra-powergate.h should be replaced
with standard reset and power domain APIs in the future.

This branch is based on (part of) the previous soc pull request.

There is only one instance of the platform data for synaptics_i2c_rmi4
in the mainline kernel, so there is no point of pretending its
variable here. The only member that has a dependency on the platform
is actually the interrupt number, and there is a field in the
i2c_client structure that gets initialized from the board info,
so we can trivially move the board_into into the platform without
knowledge of the platform_data structure.

This untangles the final bits of the prcmu code from the platform
code:

* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
  because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
  IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
  because the PRCMU does not see it.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.

Basically we are left with the two alternatives of code
placement as:

- arch/arm/mach-ux500/pm.c - this because the code is
  closely related to the GIC, and takes ownership of
  some of the registers from the PRCMU related to this
  PM functionality.

- drivers/mfd/db8500-prcmu-pm.c - because the code is
  affecting stuff in the PRCMU register range. But then
  this code needs to remap and handle GIC registers.

This patch implementation is taking the first approach.

Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.

The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.

Currently the patch is kept minimal so as not to interfere with
other work being done on refactoring this driver, but at a later
point the defines using (prcmu_base + 0xnnn) need to be replaced
by pure offset defined for (0xnnn) and the base inlined with the
readl()/writel() and similar codepaths.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.

Going forward this will be removed like this:

- The mailbox subsystem need to be merged.
  http://marc.info/?l=linux-kernel&m=136314559201983&w=2

- At this point the PRCMU clock code can be moved over to the
  ux500 clock driver in drivers/clk/ux500/* and maintained
  there in a decentralized manner.

- This early initcall and PRCMU base parameters become part of
  the ux500_clk_init() call instead.
