gpu: nvgpu: adds support for ACR dbg/prod.

ACR ucode is encrypted using different keys for prod/dbg boards.
This change adds a check to select ACR ucode based on board type.
Note: This support is added for t18x. In the sub-sequent CL, support
for T210 will be added and since ACR binaries are different for
gp10b and gm20b, a new ACR init function is created for gp10b to
accept new ACR prod/dbg binaries.
