leds: cht-wcove: Add support for breathing mode use hw_pattern sysfs API
The hw-blinking of the LED controller in the Whiskey Cove PMIC can also
be used for a hw-breathing effect.
As discussed during review of v2 of the submission of the new
leds-cht-wcove driver, the LED subsystem already supports breathing mode
on several other LED controllers using the hw_pattern interface.
Implement a pattern_set callback to implement breathing mode modelled
after the breathing mode supported by the SC27xx breathing light and
Crane EL15203000 LED drivers. The Whiskey Cove PMIC's breathing mode
is closer to the EL15203000 one then to the SC27xx one since it does
not support staying high / low for a specific time, it only supports
rise and fall times.
As such the supported hw_pattern and the documentation for this is almost
a 1:1 copy of the pattern/docs for the EL15203000 breathing mode.

Documentation: leds: MT6370: Use bullet lists for timing variables
The timing description contains list of timing pattern variables, but it
uses code block without indentation instead. Switch to bullet list as it
is better fit for this purpose.
While at it, substitute "load" for "duty" because the variables control
timing for current load into the device.

Documentation: leds: mt6370: Properly wrap hw_pattern chart
The pattern diagram (chart) of /sys/class/leds/<led>/hw_pattern is
wrapped in literal code block. However, the block indentation is
interrupted by Icurr axis label, hence below warnings:
Documentation/leds/leds-mt6370-rgb.rst:39: WARNING: Literal block ends without a blank line; unexpected unindent.
Documentation/leds/leds-mt6370-rgb.rst:41: WARNING: Line block ends without a blank line.
Documentation/leds/leds-mt6370-rgb.rst:46: WARNING: Unexpected indentation.
Documentation/leds/leds-mt6370-rgb.rst:44: WARNING: Inline substitution_reference start-string without end-string.
Fix the chart indentation by adding 4 more spaces so that the axis label
is in the code block.

leds: qcom-lpg: Require pattern to follow documentation
The leds-trigger-pattern documentation describes how the brightness of
the LED should transition linearly from one brightness value to the
next, over the given delta_t.
But the pattern engine in the Qualcomm LPG hardware only supports
holding the brightness for each entry for the period.
This subset of patterns can be represented in the leds-trigger-pattern
by injecting zero-time transitions after each entry in the pattern,
resulting in a pattern that pattern that can be rendered by the LPG.
Rework LPG pattern interface to require these zero-time transitions, to
make it comply with this subset of patterns and reject the patterns it
can't render.
