soc/intel/fsp_broadwell_de: Check if memory is 'locked'
Under certain conditions TXT can "lock" memory controller for security
purpose. This manifests itself in IMC's SMbus controller failing all SPD
data read requests. FSP does not detect error condition and fails boot
with "No memory found" issue.
TEST=tested on OCP monolake in 'locked' state
