gpu: nvgpu: add new API to get base address for sysmem/vidmem buffers
Add new API gk20a_mem_get_base_addr() which will return vidmem
base address in case of vidmem and IOVA address in case of
sysmem
Even though vidmem allocations are non-contiguous, this API
is useful (and should only be used) for allocations with one
chunk (e.g. page tables)
Also, since page tables could either reside in sysmem or vidmem,
use this API to get address of page tables
