stm32mp1_barebox_entry is given a stack canary when compiling PBL with
strong stack protector. The function can be called prior to relocation
though, so it needs to be marked as such.
This fixes boot with CONFIG_PBL_STACKPROTECTOR_STRONG=y on STM32MP1 with
generic BL33 entry point (for FIP).

Syncing device trees with Linux upstream can lead to breakage, when
the device trees are switched to newer bindings, which are not yet
supported in barebox. To make it easier to spot such issues, we want to
start applying some heuristics to flag possibly problematic DT changes.
One step towards being able to do that is to know what nodes barebox
actually consumes. Most of the nodes have a compatible entry, which is
matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE
point at it for future extraction.

Currently arch specific headers can be included with
longer possible as there won't be a single mach anymore.
Move all stm32mp specific header files to include/mach/stm32mp/ to
prepare for multi-arch support.

Now that platform_mem_driver ensures probe at mem_initcall level, we no
longer need to use the opencoded version.

The '_d' suffix was originally meant to distinguish barebox struct
names from Linux struct names. struct driver doesn't exist in Linux,
so we can rename it and remove the meaningless suffix.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

buswidth is read from HW. With nb_bytes == 2, there is a possibility
that we get a zero size out here, if driver and device are
mismatched, e.g. because barebox is booted in FIP with mismatched
external device tree.
As this runs very early before relocation, round up instead of crashing
to be a bit more on the safe side.

Failure to add one memory bank shouldn't prevent the driver from trying
to add other memory banks, but the user should be informed as this
points at a misconfiguration. Have the probe functions eventually fail
with -EBUSY in such a case.

The STM32MP DDR Controller has a very flexible way of mapping address
bits to columns/rows/banks. This is so far configured by the ARM TF-A
as part of the SDRAM setup, so we don't need to do this in barebox.
Nevertheless reading it out in barebox, allows us to determine unused
address bits and thus the total size of SDRAM configured.
Add a simple driver that parses the ddrctrl node and adds an appropriate
memory bank. This can later be used to remove explicit calls to
arm_add_mem_device in board code.

Add a barebox_arm_entry wrapper that computes the SDRAM size internally,
so boards may drop their hard-coded RAM size specifications.
