commit ce62bef8fac559e27245259882e45f19cdc293ad upstream.
- fix JIRA A7K8K-5056
- remove TEST_PATTERN write at the load patern stage earlier to WL SUP stage
- the WL SUP stage already writes this pattern to the memory, if the pattern
exist at the memory
then the algorithm will fail, since it think that there are no phase to
correct
