This reverts commit 1a67653de0dd, which caused a boot regression.
The behavior of the "drive-push-pull" in the kernel does not
match what the binding document describes. Revert Rob's patch
to make the DT match the kernel again, rather than the binding.

Boolean properties in DT are present or not present and don't take a value.
A property such as 'foo = <0>;' evaluated to true. IOW, the value doesn't
matter.
It may have been intended that 0 values are false, but there is no change
in behavior with this patch.

GPIO hog nodes must have a "hog-" prefix or "-hog" suffix according to
the DT schema. Rename all such nodes to allow validation to pass.

Regulators defined at the top level in device tree are no longer part of
a simple bus and therefore don't have a reg property. Nodes without a
reg property shouldn't have a unit-address either, so drop the unit
address from the node names. To ensure nodes aren't duplicated (in which
case they would end up merged in the final DTB), append the name of the
regulator to the node name.

Standardize on "pmic" as the node name for the PMIC on Tegra210 systems
and use consistent names for pinmux and GPIO hog nodes.

Tuple boundaries should be marked by < and > to make it clear which
cells are part of the same tuple. This also helps the json-schema based
validation tooling to properly parse this data.
While at it, also remove the "immovable" bit from PCI addresses. All of
these addresses are in fact "movable".

The standard way to do this is to list out the regulators at the top-
level. Adopt the standard way to fix validation.

The new json-schema based validation tools require SD/MMC controller
nodes to be named mmc. Rename all references to them.

The memory node requires a unit-address. For some boards the bootloader,
which is usually locked down, uses a hard-coded name for the memory node
without a unit-address, so we can't fix it on those boards.
