Add bindings for Texas Instruments' LP8864/LP8866 LED-backlight drivers.
Note that multiple channels in these models are used for load-balancing and
brightness is controlled gobally, so from a user perspective it's only one
LED.

The two properties:
- max-brightness
- default brightness
are not really required, so they can be removed from the "required"
section.
The "max-brightness" is no longer used in the current version
of the driver (it was used only in the first version).
The "default-brightness", if omitted in the DT, is managed by the
device driver, using a default value. This value depends on the dimming
mode used:
- for the "analog mode", via I2C commands, this value is fixed by
hardware (=31)
- while in case of pwm mode the default used is the last value of the
brightness-levels array.
Also the brightness-levels array is not required:
- in "analog mode", via I2C commands, the brightness-level array is
fixed by hardware (0..31).;
- in pwm dimming mode, the driver uses a default array of 0..255 and
the "default-brightness" is the last one, which is "255"
NOTE: there are no compatibility problems with the previous version,
since the device driver has not yet been included in any kernel.
Only this dt-binding yaml file is already included in the current
v6.7.0-rc1 kernel version.
No developer may have used it.
Other changes:
- improve the backlight working mode description, in the "description"
section
- update the example, removing the "max-brightness" and introducing the
"brightess-levels" property

The Monolithic Power (MPS) MP3309C is a WLED step-up converter, featuring a
programmable switching frequency to optimize efficiency.
The brightness can be controlled either by I2C commands (called "analog"
mode) or by a PWM input signal (PWM mode).
This driver supports both modes.
For device driver details, please refer to:
- drivers/video/backlight/mp3309c_bl.c

From schema: Documentation/devicetree/bindings/leds/backlight/pwm-backlight.yaml
As that backlight device node already has an "enable-gpios" property to
control the power supplied to the backlight, it sounds a bit silly to
have to add a "power-supply" property just to silence this warning. In
addition, as of commit deaeeda205 ("backlight: pwm_bl: Don't rely
on a disabled PWM emiting inactive state"), the Linux driver considers
the power supply optional.
Fix this by synchronizing the bindings with actual driver behavior by
making the "power-supply" optional.

The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.
The array of phandles case boils down to needing:
items:
maxItems: 1
The phandle plus args cases should typically take this form:
items:
- items:
- description: A phandle
- description: 1st arg cell
- description: 2nd arg cell
With this change, some examples need updating so that the bracketing of
property values matches the schema.

The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

Another round of 'allOf' removals that came in this cycle.
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
