Vedashree Vidwans	170c9552c8	tegra: hwpm: update dma buf pointer as per oot def ... OOT definition of dma_buf_vmap() is changed to accept 2 arguments. The second argumentt is used to return the dma mapping of the user buffer. However, this output pointer is expected to point to an allocated sma_buf_map structure. Add dma_buf_map structure as a member of struct tegra_hwpm_mem_mgmt.

Vedashree Vidwans	486ec4a24c	tegra: hwpm: create memory buffer structures ... 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.

Vedashree Vidwans	221e73d921	tegra: hwpm: move mem_buf functions to os folder ... PMA memory buffer functions use linux specific APIs for dma management. In an effort to make HWPM driver OS agnostic, move the memory buffer functions to os/linux path.
