media: ipu6: optimize the IPU6 MMU mapping flow
ipu6_mmu_map() operated on a per-page basis, it leads frequent
spin_lock/unlock() and clflush_cache_range() for each page, it
will cause inefficiencies especially when handling dma-bufs
with large number of pages. However, the pages are likely concentrated
pages by IOMMU DMA driver, IPU MMU driver can map the concentrated
pages into less entries in l1 table.
This change enhances ipu6_mmu_map() with batching process multiple
contiguous pages. It significantly reduces calls for spin_lock/unlock
and clflush_cache_range() and improve the performance.
