The tie between the main WCNSS driver and the IRIS driver causes a
circular dependency between the two modules. Neither part makes sense to
have on their own so lets merge them into one module.
For the sake of picking up the clock and regulator resources described
in the iris of_node we need an associated struct device. But, to keep
the size of the patch down we continue to represent the IRIS part as its
own platform_driver, within the same module, rather than setting up a
dummy device.

Allow the wcnss smd edge to be described as a child of the wcnss
remoteproc node and make the edge life cycle follow the running state of
the remoteproc.
This bond is necessary to clean up the smd state when the remote
processor is suddenly removed, and in some cases even when it shut down
in a controlled fasion.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.

In order to be able to lock a rproc driver implementations only when
used by a client, we must differ between the dereference operation of a
client and the implementation itself.
This patch brings no functional change.

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

This introduces the peripheral image loader, for loading WCNSS firmware
and boot the core on e.g. MSM8974. The firmware is verified and booted
with the help of the Peripheral Authentication System (PAS) in
TrustZone.
