Remove "locka" command. 

This command is useless, because each programming tool configures the
flash control registers before flash operations.

Show or change the status of the LOCKA bit in the chip's memory
controller. The LOCKA bit is set on POR and acts as a write-protect bit
for info segment A. This segment contains factory-configured calibration
data, and under normal circumstances, should not be changed.
If the LOCKA bit is cleared, erasing the info A segment is possible.
The LOCKA bit also affects the behaviour of the "erase all" command. If
LOCKA is set (the default), only main memory is erased. If LOCKA is
cleared, main and information memory are both erased.
