arm64: dts: qcom: Use labels with generic node names for ADC channels

As discussed in [1] it is more convenient to use a generic `channel`
node name for ADC channels while storing a friendly - board-specific
instead of PMIC-specific - name in the label, if/when desired to
overwrite the channel description already contained (but previously
unused) in the driver [2]. Follow up on the dt-bindings' `channel` node
name requirement, and instead provide this (sometimes per-board) channel
description through a label property.

Also remove all the unused label references (not to be confused with
label properties) from pm660, pmp8074 and pms405.

arm64: dts: qcom: sc7180: rename labels for DSI nodes

Currently in board files MDSS and DSI nodes stay apart, because labels
for DSI nodes do not have the mdss_ prefix. It was found that grouping
all display-related notes is more useful.

To keep all display-related nodes close in the board files, change DSI
node labels from dsi_* to mdss_dsi_*.

arm64: dts: qcom: sc7180: align TLMM pin configuration with DT schema

DT schema expects TLMM pin configuration nodes to be named with
'-state' suffix and their optional children with '-pins' suffix.

Merge subnodes named 'pinconf' and 'pinmux' into one entry, add function
where missing (required by bindings for GPIOs) and reorganize overriding
pins by boards.

Split the SPI and UART configuration into separate nodes
1. SPI (MOSI, MISO, SCLK), SPI chip-select, SPI chip-select via GPIO,
2. UART per each pin: TX, RX and optional CTS/RTS.

This allows each board to customize them easily without adding any new
nodes.

arm64: dts: qcom: sc7180-trogdor: Split out keyboard node and describe detachables

Trogdor devices that have a detachable keyboard still have a
non-detachable keyboard input device present because we include the
cros-ec-keyboard.dtsi snippet in the top-level sc7180-trogdor.dtsi file
that every variant board includes. We do this because the
keyboard-controller node also provides some buttons like the power
button and volume buttons. Unfortunately, this means we register a
keyboard input device that doesn't do anything on boards with a
detachable keyboard.

Change the node's compatible on detachables to the newly introduced
"google,cros-ec-keyb-switches" compatible to indicate that there are
only switches and no keyboard to register. Similarly, move the keyboard
include that defines the keyboard-controller node out of
sc7180-trogdor.dtsi to boards that actually have a keyboard so that the
matrix properties are not defined on boards with the switches
compatible. Future boards can either use the include approach or the
node definition approach to describe a keyboard with possible switches
or just some switches.
