leds: rgb: Add a multicolor LED driver to group monochromatic LEDs
Grouping multiple monochrome LEDs into a multicolor LED device has a few
benefits over handling the group in user-space:
- The state of the LEDs relative to each other is consistent. In other
words, if 2 threads competes to set the LED to green and red, the
end-result cannot be black or yellow.
- The multicolor LED as a whole can be driven through the sysfs LED
interface.

leds: rgb: mt6370: Correct config name to select in LEDS_MT6370_RGB
Commit 55a8a5c16eb3 ("leds: rgb: mt6370: Add MediaTek MT6370 current sink
type LED Indicator support") introduces the config LEDS_MT6370_RGB, which
selects the non-existing config LINEAR_RANGE. As the driver includes
linux/linear_range.h, it is a safe guess that the config actually intends
to select LINEAR_RANGES, which provides the library implementation for the
function prototypes defined in the linear_range header file.
Correct this naming confusion in the LEDS_MT6370_RGB config definition.

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.
