As per Intel doc #729124 Section 3.6.1 "Intel CSME Production Machine
Determination", from ADL onwards there are three criteria which
determine whether a device is in production mode:
1. Fuses are programmed
2. SPI descriptor is locked
3. Manufacturing variables are locked
When logging whether the device is in manufacturing mode, #1 and #2 are
already checked. Add a check for #3 as well.
TEST=Build and boot MTL RVP
