UADK is a framework for user applications to access hardware accelerators. UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share the same page table between IOMMU and MMU. Thereby user application can directly use virtual address for device dma, which enhances the performance as well as easy usability. Currently supported platforms: HiSilicon kunpeng920 & kunpeng930. This patch add basic framework.
