3cf755995e hwrng: xiphera - removed unnneded platform_set_drvdata()
This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

0788257aee hwrng: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was 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.

cb435fa642 hwrng: xiphera-trng: add support for XIP8001B hwrng
Xiphera XIP8001B is an FPGA-based True Random Number Generator
Intellectual Property (IP) Core which can be instantiated in
multiple FPGA families. This driver adds Linux support for it through
the hwrng interface.
