tegra: hwpm: update dma buf pointer as per oot def

Browse Source 
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.
