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.

There is a engine status register that can be used to check if the
different HW crypto engines are enabled. Check that first and then only
try to enable the engines if they are not already on.

This has a couple benefits. First we don't need to use match_data for
this. Second, this driver can now work on HS devices where the engine
control registers are read-only and writing causes a firewall exception.

Setting these individually gives a better picture of supported
functions at a glance. Plus if the list changes an unwanted
one will not accidentally get set with GENMASK.

The sa_ul_probe creates child devices using of_platform_populate(),
but these are not cleaned up in driver remove. Clean these up
by removing the child devices using of_platform_depopulate().

Simplify the platform_get_resource() and devm_ioremap_resource()
calls with devm_platform_ioremap_resource(). Also add error checking
and move up this block to simplify the cleanup in sa_ul_probe().
