If a remoteproc's firmware does not support minidump but the driver
adds an ID, the minidump driver does not collect any coredumps when
the remoteproc crashes. This hinders the purpose of coredump
collection. This change adds a fallback mechanism in the event of a
crash.

Reserved memory can be either looked up using the generic function
of_address_to_resource() or using the special of_reserved_mem_lookup().
The latter has the advantage that it ensures that the referenced memory
region was really reserved and is not e.g. status = "disabled".
of_reserved_mem also supports allocating reserved memory dynamically at
boot time. This works only when using of_reserved_mem_lookup() since
there won't be a fixed address in the device tree.
Switch the code to use of_reserved_mem_lookup(), similar to
qcom_q6v5_wcss.c which is using it already. There is no functional
difference for static reserved memory allocations.
While at it this also adds two missing of_node_put() calls in
qcom_q6v5_pas.c.

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.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The initial shutdown request to modem on SM8450 SoCs would start the
decryption process and will keep returning errors until the modem shutdown
is complete. Fix this by retrying shutdowns in fixed intervals.

Starting with Qualcomm SM8450 the metadata object shared with the secure
world during authentication and booting of a remoteproc needs to be
alive from init_image() until auth_and_reset().
Use the newly introduced "PAS metadata context" object to track this
context from load until the firmware has been booted.
In the even that load is performed but the process for some reason
doesn't reach auth_and_reset the unprepare callback is used to clean up
the allocated memory.

The resources for MSM8996 are missing power domains, and adding them
makes the resources identical to the MSM8998 ones.
Rename msm8998_adsp_resource to msm8996_adsp_resource then use it
for both chips. Also add power domains to slpi_resource_init and use
it for both chips.

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.
These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.
