Add console command to force enable console
When system is locked, the console is disabled. However, we need console
for debugging and testing. This CL uses a bit from back-up register to
indicate if the console should always be enabled. (This bit is currently
used by fake WP, which is removed in this CL.) With this, we can set
this bit with console command 'forceen 1' to ensure console is never
disabled.
To prevent device shipped in this state, the chip name is postfixed with
'-unsafe' so that the device is not able to pass HWID check.
