Instead, the IPA memory regions were defined using the ipa_mem structure. Redefine struct ipa_mem_data so it encapsulates the array of IPA-local memory region descriptors along with the count of entries in that array. Pass just an ipa_mem structure pointer to ipa_mem_init(). Rename the ipa_mem_data[] array ipa_mem_local_data[] to emphasize that the memory regions it defines are IPA-local memory.

It is built as Device Tree match data, discovered at boot time. The driver supports the Qualcomm SDM845 SoC. Data for the Qualcomm SC7180 is also defined here, but it is not yet completely supported.
