tools/testing/nvdimm: Emulate firmware activation commands
Augment the existing firmware update emulation to track activations and
validate proper update vs activate sequencing.
The DIMM firmware activate capability has a concept of a maximum amount
of time platform firmware will quiesce the system relative to how many
DIMMs are being activated in parallel. Simulate that DIMM activation
happens serially, 1 second per-DIMM, and limit the max at 3 seconds. The
nfit_test0 bus emulates 5 DIMMs so it will take 2 activations to update
all DIMMs.
