Stream and allowlist buffers are allocated by the user as dma buffers and mapped in virtual address space by the driver. The DMA and mapping functions are linux specific. Hence create memory management and allowlist linux structures. Add these linux memory structure pointers in the tegra_hwpm parent structure.
