tegra: hwpm: create memory buffer structures

Browse Source 
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.
