The db820c has 4 "user LEDs", all connected to the PMI8994. The first
three are connected to the three current sinks provided by the TRILED
and the fourth is connected to MPP2.
By utilizing the DTEST bus the MPP is fed the control signal from the
fourth LPG block, providing a consistent interface to the user.

The DB845c has 4 "user LEDs", the last one is already supported as it's
just wired to a gpio. Now that the LPG binding is in place we can wire
up the other 3 LEDs as well.

The Light Pulse Generator (LPG) is a PWM-block found in a wide range of
PMICs from Qualcomm. It can operate on fixed parameters or based on a
lookup-table, altering the duty cycle over time - which provides the
means for e.g. hardware assisted transitions of LED brightness.

`last_repeat` holds the actual value requested by the user whereas
`repeat` is a software iteration variable that is unused in hardware
patterns.
Furthermore `last_repeat` is the field returned to the user when reading
the `repeat` sysfs property. This field is initialized to `-1` which is
- together with `1` - the only valid value in the upcoming Qualcomm LPG
driver. It is thus unexpected when `repeat` with an initialization
value of `0` is passed into the the driver, when the sysfs property
clearly presents a value of `-1`.

This adds support for sdm630/636/660 modem subsystem
remote processor.
Currently an issue persists, where the remote processor will
restart itself every 40 seconds, but it seems to work otherwise.

SDM630 has two usable layer mixers (LM0, LM2) and pingpongs (PP0, PP2),
with writeback located on LM2, has no RGB pipe and does not support
source split.
SDM660 has four usable layer mixers (LM0, LM1, LM2, LM5) and
three pingpongs (PP0, PP1, PP4), with writeback located on LM2,
has no RGB pipes and does support source split; also, the HDMI
is on INTF0.
As cherry on top, let's also write the correct flush_hw_mask for
both MDP configurations to stop flushing useless and unused pipes
for performance purposes.
