This series adds the cpufreq support to the Berlin SoCs, using
cpufreq-dt.

First, the cpuclk clock is added to the BG2Q clock driver. This clock
has a divider fixed to 1, so we use a fixed factor clock here.

Then register a platform device for cpufreq-dt.

I also added the OPP table definition in the BG2Q, BG2 and BG2CD device
trees. When using a BG2Q, some bootloaders may update this table when
booting (mine doesn't).
You can switch to OPP-v2 bindings if you want. Just have a look, they are
much more powerful.. Should be in linux-next/master.
Nice!

However, it seems the OPP-v2 table takes precedence over the old one.
When a default OPP-v2 table is supplied in the device tree, if the
bootloader supplies an OPP table the old way it won't be taken into
account.

So if I understood correctly, this won't work here for the BG2Q.
