Compiling the DT file with W=1, DTC warns like follows:
Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property
Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

It would be better to name OPP nodes as opp@<opp-hz> as that will ensure
that multiple DT nodes don't contain the same frequency. Of course we
expect the writer to name the node with its opp-hz frequency and not any
other frequency.
And that will let the compile error out if multiple nodes are using the
same opp-hz frequency.

Add a new dtsi file - rk3399-opp.dtsi, to configure opp-tables
for cpu, gpu and dmc.
Add rk3399-early-opp.dtsi for board with ES1, which need limit

The rk3399 hdmi phy is supplied by the vpll directly and needs to adapt
that frequency depending on the selected resolution on the hdmi output.
For the hdmi-phy the vpll frequency is supplied unchanged without
any dividers being present there.
The vpll also is one of the sources the general display clock of the
visual output processor (vop) and as it is somewhat special for
display operations possibly also the preferred pll source. Here a divider
is available between the pll-mux and the vop clock, so that this part
can adapt the resulting frequency if needed.
So to keep the vop clock in line with the target rate, set the newly
introduced CLK_KEEP_REQ_RATE flag for the dclk_vop clocks on rk3399.

Given a hirarchy of clk1 -> [div] -> clk2, when the rate of clk1 gets
changed, clk2 changes as well as the divider stays the same. There may
be cases where a user of clk2 needs it at a specific rate, so clk2
needs to be readjusted for the changed rate of clk1.
So if a rate was requested for the clock, and its rate changed during
the underlying rate-change, with this change the clock framework now
tries to readjust the rate back to/near the requested one.
The whole process is protected by a new clock-flag to not force this
behaviour change onto every clock defined in the ccf.
