The coprocessor is running as soon as the hold boot is de-asserted.
So indicate this running state and save the resource table even
if the protective assert, to avoid autonomous reboot, is failed.
This error case should never occurs.

Use the reset function to handle the hold boot bit in RCC
with device tree handle with MCU_HOLD_BOOT identifier.
This generic reset allows to remove the two specific properties:
- st,syscfg-holdboot
- st,syscfg-tz
This patch prepares alignment with kernel device tree.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

Update the dedicated backup register to track the coprocessor state and
rely on that register to compute the .is_running() value (which expects
a return value of 0 -not 1- if the processor is running).

rproc_elf32_load_image() rely on user to send a valid address for elf loading.
Instead do a sanity check on the address passed by user. This will help
all rproc elf users to not call sanity_check explicitly before calling
elf_loading.

Introduce a new parameter "size" that accepts size of the region to
remoteproc ops callback device_to_virt(). This can enforce more checks
on the region that device_to_virt() is dealing with.
