All devices compatible with SM8150 QCE (so SM8250 and newer) do not have
clock inputs (clocks are handled by secure firmware), so explicitly
disallow the clocks in the bindings.

Binding marks several devices as compatible with IPQ4019 QCE. They have
different number of clocks, thus the fallback does not define the
clock constraints per variant and each specific compatible should have
its clocks in if:then: section.
Add missing clocks description for IPQ9574 QCE.

The core clock for the Crypto Engine block on Qualcomm SoCs SM6115 and
QCM2290 are provided via the RPM block.
So mark the compatibles for these SoCs to indicate that only 'core'
clock is required for such SoCs.

Currently the compatible list available in 'qce' dt-bindings does not
support SM8150 and IPQ4019 SoCs directly which may lead to potential
'dtbs_check' error(s).
Fix the same.

On newer Qualcomm SoCs the crypto engine clocks are enabled by default
by security firmware. To drop clocks and clock-names from the list of
required properties use 'qcom,sm8150-qce' compatible name.
The change is based on Neil Armstrong's observation and an original change.

Introduce a generic IP family compatible 'qcom,qce' and its two derivatives
based on SoC names rather than on IP versions. Having a generic compatible
is only partially sufficient, the QCE IP version can be discovered in
runtime, however there are two known groups of QCE IP versions, which
require different DT properties, these two groups are populated with SoC
based compatibles known at the moment.
Keep the old compatible 'qcom,crypto-v5.1' and document an existing and
already used but not previously documented compatible 'qcom,crypto-v5.4'
for backward compatibility of DTB ABI, mark both of the compatibles as
deprecated.
The change is based on the original one written by Bhupesh Sharma, adding
a generic family compatible is suggested by Neil Armstrong.

Add 'interconnects' and 'interconnect-names' as optional properties
to the device-tree binding documentation for Qualcomm crypto IP.
These properties describe the interconnect path between crypto and main
memory and the interconnect type respectively.
