Those two fields are used to store the per SPT page of tx/rx descriptors send to the firmware for cookie conversion. Right now they are in struct ath12k_spt_info which means they are duplicated PPT page times while we only need one instance of them. This works for now as we always use the first spt_info as a global storage for all PPT pages. Let's move them into struct ath12k_dp where they belong, alongside of the spt_info array they are tied to, to avoid waisting a good bit of memory.
