interconnect: qcom: sm8650: remove regmap config for mc_virt & clk_virt

The mc_virt & clk_virt nodes are virtual and doesn't have associated registers,
thus the regmap config will fail with:
qnoc-sm8650 interconnect-0: error -EINVAL: invalid resource (null)

Remove the regmap config since QoS will never be applied to those virtual
nodes.
