This series adds the IPA driver as a possible target when
the COMPILE_TEST configuration is enabled.  Two small changes to
dependent subsystems needed to be made for this to work.

David/Jakub, it would be best to take all three of these patches
through the same tree.  I have discussed this with Bjorn and he
agreed to ack them, and I request that you take them through
net-next.

Thanks.

Stub functions are defined for SSR notifier registration in case
QCOM_RPROC_COMMON is not configured.  As a result, code that uses
these functions can link successfully even if the common remoteproc
code is not built.

Code that registers an SSR notifier function likely needs the
types defined in "qcom_rproc.h", but those are only exposed if
QCOM_RPROC_COMMON is enabled.

Rearrange the conditional definition so the qcom_ssr_notify_data
structure and qcom_ssr_notify_type enumerated type are defined
whether or not QCOM_RPROC_COMMON is enabled.

Define stub functions for the exposed MDT functions in case
QCOM_MDT_LOADER is not configured.  This allows users of these
functions to link correctly for COMPILE_TEST builds without
QCOM_SCM enabled.

Arrange for the IPA driver to be built when COMPILE_TEST is enabled.

Update the help text to reflect that we support two Qualcomm SoCs.

@Jakub, @Dave, as this is a prerequisite for allowing IPA to be compile
tested feel free to merge it together with patch 3.

I think I just need to define at the top of "gsi_trans.h":
    struct page;

I'll submit v2 of this series, with this one change
(assuming it's the correct fix).  I will incorporate
Bjorn's review tags on the first two patches.
