arm64: dts: rockchip: move mmc aliases to board dts on rk3399

As suggested by Arnd Bergmann, the newly added mmc aliases
should be board specific, so move them from the general dtsi
to the individual boards.

arm64: dts: rockchip: remove properties from spdif node RK3399 Excavator

An expermental test with the command below gives this error:

'i2c-scl-falling-time-ns', 'i2c-scl-rising-time-ns'
are not valid properties for 'spdif' nodes, so remove them.

arm64: dts: rockchip: clean up the abuse of disable-wp

only, but that is what it was designed for in the first place.

Remove all disable-wp from emmc or sdio controller.

arm64: dts: rockchip: fix graph_port warning on rk3399 bob kevin and excavator

Ports are described by child 'port' nodes contained in the device node.
'ports' is optional and is used to group all 'port' nodes which is not
the case here.

This patch fixes the following warnings:

arch/arm64/boot/dts/rockchip/rk3399-gru-bob.dts:25.9-29.5: Warning (graph_port): /edp-panel/ports: graph port node name should be 'port'
arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts:46.9-50.5: Warningi (graph_port): /edp-panel/ports: graph port node name should be 'port'
arch/arm64/boot/dts/rockchip/rk3399-sapphire-excavator.dts:94.9-98.5: Warning (graph_port): /edp-panel/ports: graph port node name should be 'port'

arm64: dts: rockchip: generalize rk3399 #sound-dai-cells

The soc spdif and i2s controllers always only have one compontent, so
always require #sound-dai-cells to be 0. Therefore there is no need to
duplicate this property in individual boards.

So move them to rk3399.dtsi.

Update all 64bit rockchip devicetree files to use SPDX-License-Identifiers.

All devicetrees claim to be either GPL or X11 while the actual license
text is MIT. Therefore we use MIT for the SPDX tag as X11 is clearly
wrong.
