Changes from v5 to v6: - Updated function "k3_ringacc_ring_reset_raw" in [PATCH v5 04/10] to reset only ring size field in ring configuration register as pointed out by Alexander Sverdlin. - Added a new patch [PATCH 05/11] to reset only qmode in "k3_ringacc_ring_reconfig_qmode_raw" function as it was resetting other fields in ring configuration register. - Moved function to enable cache before probing CPSW driver as suggested by Andrew. - Added Reviewed-by tags from Alexander Sverdlin and Sumit Garg.

Initialize base address of ring config registers required to natively setup ring cfg registers in the absence of Device Manager (DM) services at R5 SPL stage. Since register property is defined as "ring" for PKTDMA and "cfg" for UDMA, configure base address of ring configuration register accordingly.
