dt-bindings: arm-smmu: Add generic qcom,smmu-500 bindings

Add generic bindings for the Qualcomm variant of the ARM MMU-500. It is
expected that all future platforms will use the generic qcom,smmu-500
compat string in addition to SoC-specific and the generic arm,mmu-500
ones. Older bindings are now described as deprecated.

Note: I have split the sdx55 and sdx65 from the legacy bindings. They
are not supported by the qcom SMMU implementation. I can suppose that
they are using the generic implementation rather than the
Qualcomm-speicific one.
