It might be useful to know what hardware version of the OCMEM block the
SoC contains. Add a debug print for that.

Now that SMEM exports a helper to get the SMEM SoC ID lets utilize it.
Currently qcom_cpufreq_get_msm_id() is encoding the returned SMEM SoC ID
into an enum, however there is no reason to do so and we can just match
directly on the SMEM SoC ID as returned by qcom_smem_get_soc_id().

SMEM SoC ID-s are now stored in DT bindings so lets use those instead of
defining them in the driver again.

Introduce a helper to return the SoC SMEM ID, which is used to identify the
exact SoC model as there may be differences in the same SoC family.
Currently, cpufreq-nvmem does this completely in the driver and there has
been more interest expresed for other drivers to use this information so
lets expose a common helper to prevent redoing it in individual drivers
since this field is present on every SMEM table version.

SMEM has been GPL licensed from the start, and there is no reason to use
EXPORT_SYMBOL() so switch to the GPL version.

Move SMEM item struct and related defines to a header in order to be able
to reuse them in the SMEM driver instead of duplicating them.

Commit ebeb20a9cd3f ("soc: qcom: mdt_loader: Always invoke PAS
mem_setup") dropped the relocate check and made pas_mem_setup run
unconditionally. The code was later moved with commit f4e526ff7e38
("soc: qcom: mdt_loader: Extract PAS operations") to
qcom_mdt_pas_init() effectively losing track of what was actually
done.
The assumption that PAS mem_setup can be done anytime was effectively
wrong, with no good reason and this caused regression on some SoC
that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that
effectively broke resulting in remoteproc silently die and ath11k not
working.
On this SoC FW relocate is not enabled and PAS mem_setup was correctly
skipped in previous kernel version resulting in correct bringup and
function of remoteproc and ath11k.
To fix the regression, reintroduce the relocate check in
qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is
not enabled.

Introduce a driver to query and expose detailed, per-subsystem (as opposed
to the existing qcom_stats driver which exposes SoC-wide data) about low
power mode states of a given RPM master. That includes the APSS (ARM),
MPSS (modem) and other remote cores, depending on the platform
configuration.
This is a vastly cleaned up and restructured version of a similar
driver found in msm-5.4.
