Add 'interconnects' and 'interconnect-names' to the device-tree binding
documentation for qcom crypto IP.

These properties describe the interconnect path between crypto and main
memory and the interconnect type respectively.

While at it also move 'clocks' to the optional properties sections,
as crypto IPs on SoCs like sm8150, sm8250, sm8350 (and so on), don't
require linux to setup the clocks (this is already done by the secure
firmware running before linux).
