memory: 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 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.

memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe()

The break of for_each_available_child_of_node() needs a
corresponding of_node_put() when the reference 'child' is not
used anymore. Here we do not need to call of_node_put() in
fail path as '!match' means no break.

While the of_platform_device_create() will created a new
reference by 'child' but it has considered the refcounting.

memory: pl353: Fix error return code in pl353_smc_probe()

When no child nodes are matched, an appropriate error code -ENODEV should
be returned. However, we currently do not explicitly assign this error
code to 'err'. As a result, 0 was incorrectly returned.

memory: pl353-smc: Let lower level controller drivers handle inits

There is no point in having all these definitions at the SMC bus level,
these are extremely tight to the NAND controller driver implementation,
are not particularly generic, imply more boilerplate than needed, do
not really follow the device model by receiving no argument and some of
them are actually buggy.

Let's get rid of these right now as there is no current user and keep
this driver at a simple level: only the SMC bare initializations.

The NAND controller driver which I am going to introduce will take care
of redefining properly all these helpers and using them directly.

amba: Make the remove callback return void

All amba drivers return 0 in their remove callback. Together with the
driver core ignoring the return value anyhow, it doesn't make sense to
return a value here.

Change the remove prototype to return void, which makes it explicit that
returning an error value doesn't work as expected. This simplifies changing
the core remove callback to return void, too.
