Add IPA client named ipa_wigig. This client provides API for the 11AD protocol driver to configure IPA for 11AD clients offload. Currently up to 4 clients are supported. The clients share the RX pipe and have a separate TX pipe. The ipa_wigig client shall SMMU map 11AD HW registers and buffers and shall configure IPA uC and GSI for 11AD clients offload.
