We need the signal from wcnss_ctrl indicating that the firmware is up
and running before we can communicate with the other components of the
chip. So make these other components children of the wcnss_ctrl device,
so they can be probed in order.
The process seems to take between 1/2-5 seconds, so this is done in a
worker, instead of holding up the probe.

This merges the Qualcomm SOC tree with the net-next, solving the
merge conflict in the SMD API between the two.

Introduce compile stubs for the SMD API, allowing consumers to be
compile tested.

By passing the smd channel reference to the callback, rather than the
smd device, we can open additional smd channels from sub-devices of smd
devices.
Also updates the two smd clients today found in mainline.

With the qcom_smd_open_channel() API we allow SMD devices to open
additional SMD channels, to allow implementation of multi-channel SMD
devices - like Bluetooth.
Channels are opened from the same edge as the calling SMD device is tied
to.

Introduce a setter for the callback function pointer to clarify the
locking around the operation and to reduce some duplication.

Passing a void ** almost always requires a cast at the call site.
Instead of littering the code with casts every time this function
is called, have qcom_smem_get() return a void pointer to the
location of the smem item. This frees the caller from having to
cast the pointer.

Implement a id_table based driver maching mechanism for drivers that
binds to fixed channels and doesn't need any additional configuration,
e.g. IPCRTR and DIAG.

Driver for the Resource Power Manager (RPM) found in Qualcomm 8974 based
devices.
The driver exposes resources that child drivers can operate on; to
implementing regulator, clock and bus frequency drivers.
