This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:
* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
stopping the CPU while we configure PLL0's rate, ACLK is reparented
to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
so we instead just disallow changing PLL1's rate after relocation (when
we are using the AISRAM).

This is effectively a complete rewrite to remove all dependency on CCF.
The code is now smaller, and so is the binary. It also takes up less memory
at runtime (since we don't have to create 40 udevices). In general, I am
much happier with this driver as much of the complexity and late binding
has been removed.
The k210_*_params structs which were previously used to initialize CCF
clocks are now used as the complete configuration. Since we can write our
own division logic, we can now do away with several "half" clocks which
only existed to provide constant factors of two.
The clock IDs have been renumbered to remove unused clocks. This may not be
the last time they are renumbered, since we have diverged with Linux. There
are also still a few clocks left out which may need to be added back in.
In general, I have tried to leave out behavioral changes. However, there is
a small bugfix regarding ACLK. According to the technical reference manual,
its mux comes *after* its divider (which is present only for PLL0). This
would have required yet another intermediate clock to fix with CCF, but
with the new driver it is just 2 lines of code :)

Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc
state for SPL only") it has been impossible to set clock defaults before
relocation. This is annoying on boards without SPL, since there is no way
to set clock defaults before U-Boot proper. In particular, the aisram rate
must be changed before relocation on the K210, since U-Boot will hang if we
try and change the rate while we are using aisram.
To get around this, extend the stage parameter to allow force setting
defaults, even if they would be otherwise postponed for later. A device
tree property was decided against because of the concerns in the original
commit thread about the overhead of repeatedly parsing the device tree.
