The device tree specification recommends that generic name should be
used for nodes.  So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

DEBUG_FS used to be selected by COMMON_CLK_DEBUG, which was enabled
by tegra_defconfig. However, this config option no longer exists, so
no longer selects DEBUG_FS, and nothing else selects it either. So,
"make tegra_defconfig" no longer enables DEBUG_FS in .config.

Rebuild tegra_defconfig on top of next-20140424, while manually
re-enabling DEBUG_FS.

Reasons for removed entries are:
- I2C_MUX: selected by MEDIA_SUBDRV_AUTOSELECT
- DRM_PANEL: selected by DRM_TEGRA
- NEW_LEDS: selected by many things; at least VT
- LEDS_CLASS: selected by many things; at least VT

multi_v7_defconfig was missing a large number of options that were in
tegra_defconfig. This patch adds them. The changes fall into the
following categories:

* Enable more Tegra SoC options/drivers.
* Enable more drivers for Tegra boards.
* Enable more options that are useful for running distros.

The patch removes a few lines as well, simply because those options are
now selected by something else, and "make savedefconfig" removes them. I
verified that the options appear in .config after
"make multi_v7_defconfig".

The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions
causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address.

This can happen in practice on ARM where foreign pages can be above 4GB even
though the local kernel does not have LPAE page tables enabled (which is
totally reasonable if the guest does not itself have >4GB of RAM). In this
case the kernel still maps the foreign pages at a phys addr below 4G (as it
must) but the resulting DMA address (returned by the grant map operation) is
much higher.

This is analogous to a hardware device which has its view of RAM mapped up
high for some reason.

This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM
systems with more than 4GB of RAM.

Some SoC have MMIO regions that are shared across orthogonal
subsystems. This commit implements a possible solution for the
thread-safe access of such regions through a spinlock-protected API.

Concurrent access is protected with a single spinlock for the
entire MMIO address space. While this protects shared-registers,
it also serializes access to unrelated/unshared registers.

We add relaxed and non-relaxed variants, by using writel_relaxed and writel,
respectively. The rationale for this is that some users may not require
register write completion but only thread-safe access to a register.
