dt-bindings: qcom-qce: Add new SoC compatible strings for Qualcomm QCE IP

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.
