ARM: tegra: Device tree changes for v4.13-rc1

This removes support for the Whistler board, which only a handful of
people ever had access to and which doesn't provide any features over
other Tegra20 devices that we support.

Also this cleans up some PCI related device tree content in preparation
for a future DTC release that has additional checks for the PCI bus.

arm64: tegra: Device tree changes for v4.13-rc1

This adds the CCPLEX cluster on Tegra186, which is used to initiate CPU
frequency and voltage transitions.

Also included is a bit of cleanup for PCI related device tree content,
in preparation for a future DTC release that has additional checks for
the PCI bus.

Merged, but does the bpmp-abi.h really belong in include/soc? Seems like most
of it is internal ABI for whatever abstraction communicates with bpmp, in this
case powergate. Locating it as a headerfile under drivers/soc/tegra/ seems to
make more sense. Care to move it?

The header is used by all drivers that communicate with the BPMP, and 
they are scattered around the tree in their corresponding modules - e.g. 
drivers/clk/tegra/clk-bpmp.c, or the upcoming 
drivers/thermal/tegra/bpmp-thermal.c.

Having to expose the command format to all drivers seems a bit odd, compared to
providing helpers from drivers/soc to perform the commands/actions.

I guess most users aren't in-tree yet (tried grepping around for some of the
struct names and found no users), so I guess we'll see over time how it
develops. It could always be refactored later, if needed.
