[ARM] tegra: add nvrm transport interface

add nvrm transport kernel APIs and nvrpc device node access to
it, to support basic multimedia and AVP access

add enough nvrmmodule functions to get RM transport bootstrapped
and to support resetting the AVP (which is needed after the AVP
kernel is loaded by nvrm_daemon).
