Documentation: arm: Fix typo in the idle-states bindings examples

The idle-states bindings mandate that the entry-method string
in the idle-states node must be "psci" for ARM v8 64-bit systems,
but the examples in the bindings report a wrong entry-method string.
Owing to this typo, some dts in the kernel wrongly defined the
entry-method property, since they likely cut and pasted the example
definition without paying attention to the bindings definitions.

This patch fixes the typo in the DT idle states bindings examples and
respective dts in the kernel so that the bindings and related dts
files are made compliant.

Pull ARM devicetree updates from Arnd Bergmann:
"This is the set of device tree changes, mostly covering new hardware
support, with 577 patches touching a little over 500 files.

There are five new Arm SoCs supported in this release, all of them for
existing SoC families:

- Realtek RTD1195, RTD1395 and RTD1619 -- three SoCs used in both NAS
devices and Android Set-top-box designs, along with the
"Horseradish", "Lion Skin" and "Mjolnir" reference platforms; the
Mele X1000 and Xnano X5 set-top-boxes and the Banana Pi BPi-M4
single-board computer.

- Renesas RZ/G1H (r8a7742) -- a high-end 32-bit industrial SoC and
the iW-RainboW-G21D-Qseven-RZG1H board/SoM

- Rockchips RK3326 -- low-end 64-bit SoC along with the Odroid-GO
Advance game console

Newly added machines on already supported SoCs are:
