soc: ti: k3-ringacc: add request pair of rings api.
Add new API k3_ringacc_request_rings_pair() to request pair of rings at once, as in the most cases Rings are used with DMA channels, which need to request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and one to receive completions (RX/TX CQ). This will allow to simplify Ringacc API users.
