A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

Neither Tegra114 nor Tegra124 allow "low power mode" to be configured
on SDIO1 or SDIO3 drive groups. Remove the attempt to configure that
option from the Dalmore and Venice2 DTs.
The Venice2 DT contained duplicate configurations for most sdmmc1_*
pins. Remove the duplicate pins from one of the nodes, and fix the
configuration since the remaining clk pin is output-only.

Tegra124 can support 4GB of RAM. With that much RAM (plus some memory-
mapped IO peripherals), more than 32-bits of physical address space is
required. Hence, convert all Tegra124 DTs to use 2 DT cells for address
space.
(I think this was suggested by Olof Johansson, but I'm not 100% sure)

Some of the regulators and the relationships to other regulators are
wrong. This commit attempts to rectify this by making them more similar
to what the schematics contain. This starts by adding a +VDD_MUX supply
that represents the 12V input and derives the main +3.3V_SYS and +5V_SYS
supplies from that. The majority of the other regulators derive from one
of those three.
While at it, rename the regulators to match the names in the schematics
to make them easier to match up.

Both USB_VBUS_EN0 and USB_VBUS_EN1 are configured the same way, so they
can be combined into a single node. While at it, don't configure them as

configure them as pull-up either.

Tegra124 has 4 MMC controllers just like previous versions of the SoC.
Note that there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW.
Also enable the relevant controllers in the Venice2 board DT.
