As before the patchset has been tested to boot DB845c (with splash screen) and
Lenovo Yoga C630 (with EFI framebuffer).

Changes since v3:
- Extracted from different patch in v3.
- Now configures the stream as BYPASS, rather than translate, which should work
for platforms with working S2CR handling as well.

by the means of
configuring the stream for translation using a reserved and disabled
context bank.
Also circumvent the problem of configuring faulting streams by
configuring the stream as bypass.

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.

Thanks for pointing that out, replacing
While the signal on GPIO4 to drive the backlight controller indeed is
pulse width modulated its purpose is specifically to control the
brightness of a backlight.
Drop the #pwm-cells and instead expose a new property to configure the
granularity of the backlight PWM signal.
