Subject: [PATCH 00/14] Multiple addition and improvement to ipq8064 gcc

This is an attempt in making the ipq8064 SoC actually usable. Currently
many feature are missing for this SoC and devs user off-the-tree patches
to make it work (example patch for missing clock, patch for cpufreq
driver, patch to add missing node in the dts)

I notice there was some work in modernizing the gcc driver for other
qcom target but this wasn't done for ipq806x. This does exactly this, we
drop any parent_names stuff and we switch to the parent_data way. We
also drop the pxo and cxo source clk from gcc driver and we refer to the
dts for it.

This also add all the missing feature for the nss cores and the
cryptoengine in them. It does also introduce the required flags to make
the RPM actually work and NOT reject any command. There was an attempt
in declaring these clock as core clock in the dts but this ends up in no
serial as the kernel makes these clock not accessible. We just want to
make the kernel NOT disable them if unused nothing more.

At the end we update the ipq8064 dtsi to add the pxo and cxo tag and
declare them in gcc and also fix a problem with tsens probe.
