accel/ivpu: Rename and cleanup MMU600 page tables
Simplify and unify naming convention in MMU600 page tables configuration. All DMA addresses in page tables directly accessed by VPU are called with _dma sufix and all CPU pointers to those page tables have _ptr sufix. Base pointers used to do a page walk on the CPU have corresponding names: pud_ptrs (pointers used to get access to PUD DMA) pmd_ptrs (pointers used to get access to PMD DMA) pte_ptrs (pointers used to get access to PTE DMA) with the following convention: u64 *pud_dma_ptr = pud_ptrs[pgd_idx]; *pud_dma_ptr = pud_dma; u64 *pmd_dma_ptr = pmd_ptrs[pgd_idx][pud_idx]; *pmd_dma_ptr = pmd_dma; u64 *pte_dma_ptr = pte_ptrs[pgd_idx][pud_idx][pmd_idx]; *pte_dma_ptr = pte_dma; On the way change to coherent dma allocation, _wc is only valid on ARM and was used by mistake.
