The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

When the platform was booted with the involved clocks enabled the
clk_set_rate() of the link and pixel clocks will perculate to the
children, which will fail to update because the PHY driver has just shut
down the PLL.
Postpone the clock rate updates until the PLL is back online to avoid
reconfiguring the clocks while the PLL is not ticking.

The eDP phy can be used to drive either eDP or DP output, with some
minor variations in some of the configuration and seemingly a need for
implementing swing and pre_emphasis calibration.
Introduce a config object, indicating if the phy is operating in eDP or
DP mode and swing/pre-emphasis calibration to support this.

Many recent Qualcomm platforms comes with native DP and eDP support.
This consists of a controller in the MDSS and a QMP-like PHY.
While similar to the well known QMP block, the eDP PHY only has TX lanes
and the programming sequences are slightly different. Rather than
continuing the trend of parameterize the QMP driver to pieces, this
introduces the support as a new driver.
The registration of link and pixel clocks are borrowed from the QMP
driver. The non-DP link frequencies are omitted for now.
The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only
the prior is supported for now.
