The OPPs for the A83T CPU cores were added in v4.17 in commit 2db639d8
("ARM: dts: sun8i: a83t: add stable OPP tables and CPUfreq"), but board
level regulator supplies for the CPU clusters were only added for the
TBS-A711 tablet. This means the other A83T boards do not benefit from
voltage scaling, or worse, if the implementation does not scale the
frequency when the voltage is fixed, no benefit at all.

Add board level CPU cluster power supplies to all the A83T development
boards, so they can have proper dynamic CPU voltage and frequency scaling.

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.

Fix other missing properties (clocks, OPP, clock latency) as well to
make it all work.

KCOV is code coverage collection facility used, in particular, by
syzkaller system call fuzzer.  There is some interest in using syzkaller
on arm devices.  So port KCOV to arm.

On implementation level this merely declares that KCOV is supported and
disables instrumentation of 3 special cases.  Reasons for disabling are
commented in code.

Tested with qemu-system-arm/vexpress-a15.
