gpu: nvgpu: Add function to set falcon dmactl register

Add nvgpu_utf_falcon_set_dmactl() function in falcon UTF
to set the falcon dmactl register with desired value
required for pmu reset test

Also, update the register size for falcon from 0x300 to 0x400
for including pmu reset register.

Rename userspace/units/facon/falcon folder to
userspace/units/facon/falcon_tests
