ARM: tegra: Convert PMC to a driver
This commit converts the PMC support code to a platform driver. Because
the boot process needs to call into this driver very early, also set up
a minimal environment via an early initcall.

ARM: tegra: remove common.c
common.c was create to contain code shared across the various Tegra board
files. There is now only one board file, tegra.c. So, move the code there.
One exception is the PMC reboot routine, which moves to pmc.c, and now
takes advantage of the 'standard' tegra_pmc_readl/writel functions.

PCI: tegra: Move PCIe driver to drivers/pci/host
Move the PCIe driver from arch/arm/mach-tegra into the drivers/pci/host
directory. The motivation is to collect various host controller drivers
in the same location in order to facilitate refactoring.
The Tegra PCIe driver has been largely rewritten, both in order to turn
it into a proper platform driver and to add MSI (based on code by
Krishna Kishore <kthota@nvidia.com>) as well as device tree support.

This patch fixes the build error when ARCH_TEGRA_114_SOC is enabled
and ARCH_TEGRA_3x_SOC is disabled.
This provides Tegra114 with its own tegra114_init_early() instead of
making use of tegra30_init_early() so that T114 build doesn't depend
on T3x anymore.

ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html
Includes mach-omap2 fixes from Igor Grinberg.

ARM: tegra: paz00: enable WiFi rfkill when booting from device tree
There currently aren't bindings for a WiFi rfkill button, and defining
a good binding is non-trivial. Manually register this "device" when
booting from device tree, in order to bring DT support to the same
feature level as board files, which will in turn allow board files to be
deprecated.

ARM: tegra: harmony: init regulators, PCIe when booting from DT
There currently aren't bindings for the Tegra PCIe controller. Work on
this is in progress, but not yet complete. Manually initialize PCIe when
booting from device tree, in order to bring DT support to the same
feature level as board files, which will in turn allow board files to be
deprecated.
PCIe on Harmony requires various regulators to be registered and enabled
before initializing the PCIe controller. Note that since the I2C
controllers are instantiated from DT, we must use i2c_new_device() to
register the PMU rather than i2c_register_board_info().

arm/tegra: Delete tegra_init_clock()
tegra_init_clock() is written to call tegra2_init_clocks(), which only
exists if Tegra20 support is enabled. This breaks the build of a
Tegra30-only kernel.
tegra_init_clock() isn't actually used any more; tegra20_init_early()
calls tegra2_init_clocks() directly. So, just delete this function.
