Assume jumper placed on EVB JP41 1-3 to connect GPIO 0156 and 157.
Root cause is a bug in the GPIO driver. Test asks driver to disconnect GPIO 0157. Test then asks driver to set GPIO 0157 to output high. Driver does not clear GPIO control register power gate field leaving the pin powered off (disconnected).
