Device tree binding for NVIDIA Tegra have traditionally carried the
"nvidia," vendor prefix in the filename. A couple of odd ones don't, so
fix them up for consistency.

Also rename existing bindings to reflect the first compatible value that
they document. This wasn't done consistently either.

When Tegra124 support was first merged the unit-addresses of all devices
were listed with a "0," prefix to encode the reg property's second cell.
It turns out that this notation is not correct, and the "," separator is
only used to separate fields in the unit address (such as the device and
function number in PCI devices), not individual cells for addresses
with more than one cell.

Commit eb3fcf00 ("dt-bindings: consolidate interrupt controller
bindings") moved the binding documentation for the ARM GIC from
arm/gic.txt to interrupt-controller/arm,gic.txt. However, there are
still some binding documents referring to the old path. Update these
binding documents to use the correct location.

Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices.

Rename sub-nodes to avoid new dtc unit address warnings when copied.

While at it, adopt the dashes convention for the node name.

With this macro any user can easily iterate over a list of
phandles. The patch also converts __of_parse_phandle_with_args()
to make use of the macro.

The of_count_phandle_with_args() function is not converted,
because the macro hides the return value of of_phandle_iterator_init(),
which is needed in there.

The index = -1 case in __of_parse_phandle_with_args() is
used to just return the number of phandles. That special
case needs extra handling, so move it to the place where it
is needed: of_count_phandle_with_args().

This allows to further simplify __of_parse_phandle_with_args()
later on.
