Add sm1 support the axg audio clock controllers. This new version is
indeed derived from the previous generation, as always, adding a few
new clocks to the mix.
The number of gates now exceeds 32 and do not fit in a single register.
Unfortunately, designers chose to introduce the new gate register
immediately after the original one, at the beginning of the register
space, shifting all the master clock register offsets.
The sm1 also introduce a few mux and divider on the top clock path,
possibly to lower the peripheral clocks of the audio blocks if
necessary.

The peripheral clock on the sm1 goes through some muxes
and dividers before reaching the audio gates. To model that,
without repeating our self too much, the "top" clock signal
is introduced and will serve as a the parent of the gates.
On the axg and g12a, the top clock is just a pass-through to
the audio peripheral clock provided by the main controller.

Rearrange the macro definition of the clocks of the axg-audio
controller. Also, the sm1 variant will feature tiny modification
of different blocks in this controller. Because of that, we need
to fallback to the old way of defining parent for some of the
clocks, using signal name.

Meanwhile, no need to define PLL clock structure for every

Armada 3700 PCIe IP relies on the PCIe clock managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their registers at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().
Device link support in the clock framework enforce that the clock
driver's resume() callback will be called before the PCIe
driver's. But, any resume_noirq() callback will be called before all
the registered resume() callbacks.
The solution to support PCIe resume operation is to change the
"priority" of this clock driver PM callbacks to "_noirq()".

Merge active entropy generation updates.
This is admittedly partly "for discussion". We need to have a way
forward for the boot time deadlocks where user space ends up waiting for
more entropy, but no entropy is forthcoming because the system is
entirely idle just waiting for something to happen.
While this was triggered by what is arguably a user space bug with
GDM/gnome-session asking for secure randomness during early boot, when
they didn't even need any such truly secure thing, the issue ends up
being that our "getrandom()" interface is prone to that kind of
confusion, because people don't think very hard about whether they want
to block for sufficient amounts of entropy.
The approach here-in is to decide to not just passively wait for entropy
to happen, but to start actively collecting it if it is missing. This
is not necessarily always possible, but if the architecture has a CPU
cycle counter, there is a fair amount of noise in the exact timings of
reasonably complex loads.
We may end up tweaking the load and the entropy estimates, but this
should be at least a reasonable starting point.
As part of this, we also revert the revert of the ext4 IO pattern
improvement that ended up triggering the reported lack of external
entropy.
* getrandom() active entropy waiting:
Revert "Revert "ext4: make __ext4_get_inode_loc plug""
random: try to actively add entropy rather than passively wait for it
