msm: krait-regulator: handle efuse differences

Scaling factor version is valid for
- 8974 based devices when the version bits read 1
- 8974pro based devices when the version bits read 1 or 2
- 8084 based devices when the version bits read 0
- 8092 based devices when the version bits read 0

Moreover the three bit scaling factor data for
- 8974 based devices starts at bit 16
- 8974pro based devices starts at bit 16
- 8084 based devices starts at bit 14
- 8092 based devices starts at bit 14

Update the code to handle these differences.

msm: krait-regulator: fix unnecessary calls to switch to LDO

When asked to set a LDO voltage the driver rounds it up to
the nearest step value. However, when checking if the requested voltage
is already set it doesn't account for the rounding up.

Fix this by rounding up the requested value, which avoids
unnecessary calls to set the LDO voltage and switch to LDO.

msm: krait-regulator: add support for auto mode

On certain PMIC the AUTO mode for the ganged regulator operates
within spec. Allow the driver to use the auto mode and skip
controlling  PFM/PWM mode switching.

Enable support for using auto mode configuration.

mdss: Avoid panel ON commands during boot up for command mode

In command mode, when continuous splash is enabled, we do not
send the panel OFF commands through the SPLASH_BEGIN callback.
Avoid the SPLASH_FINISH callback also for command mode since
panel ON commands are not required to be sent. This avoids
unnecessary warnings during boot up.

msm: mdss: increase height constraints for panel resolution

MDP is able to support higher resolution and is only limited in height
by the MDP clock rate. There is already check in place for the MDP clock
requirement, however need to update phase step calculation to handle
proper overflow conditions for these higher resolution according to
hardware constraints based on potential overflow while scaling with some
phase steps. At the same time hardware is able to handle some conditions
that are currently failed, so enable these to allow more cases that can
go through MDP.

msm: mdss: Enable solid fill on pipe

Add support to enable solid fill on pipe with an option to
configure fill-color by userspace. This support does not confine
to background pipe and can be used to enable solid fill on any source
surface processing pipes irrespective of the z-order.
This support can be used in requirements involving constant
color layers.

All the configuration up until MDP flush is double buffered. This means
we are able to do all hardware programming without settings taking
effect until flush happens. Perform all programming, wait for fences
and wait for previous frame is done just before the flush in order to
reduce the time between last frame done and kickoff of next one.

ARM: dts: msm: define max supported memory bandwidth for display

As display resolutions increase, the memory bandwidth requirement
increases as the number of layers supported increase. With these high
memory requirements it's not possible to sustain high memory bandwidth
requirement past a certain threshold without potentially underflowing.
These bandwidth thresholds are different across targets, define these
according to system level profiling results.
