Mirroring the type-based allocation now in use for the kmalloc family of
APIs, provide the same for the devm_kmalloc family of APIs. This will
allow for future plumbing of type information (e.g. alignment) into the
underlying allocations. This immediately gains type check on return
values (instead of the prior "void *" return type).

devres_for_each_res() is only used by .../firmware_loader/main.c, which
already includes base.h.
The usage of devres_for_each_res() by code outside of driver-core is
questionable, hence move it to base.h.

Move devm_alloc_percpu() and related to devres.h where it belongs.

Provide a function similar to devm_strdup_const() but for copying blocks
of memory that are likely to be placed in .rodata.

In some code we would like to know if the action in device managed resources
was added by devm_add_action() family of calls. Introduce a helper for that.

We have a newly created header linux/device/devres.h that gathers
device managed APIs, so users won't need to include entire device.h
for only these ones. Move devm_*_action*() APIs to devres.h as well.

Introduce '_array' variant of devm_kmemdup() which is more robust and
consistent with alloc family of helpers.

device.h is a huge header which is hard to follow and easy to miss
something. Improve that by splitting devres APIs to device/devres.h.
In particular this helps to speedup the build of the code that includes
device.h solely for a devres APIs.
While at it, cast the error pointers to __iomem using IOMEM_ERR_PTR()
and fix sparse warnings.
