kinetis_ftfx_command() did not use other struct flash_bank* members
than base->target. Switching first parameter to struct target*
enables use of kinetis_ftfx_command() without unnecessary bank
getting and probing.

Removed kinetis_securing_test: kind of dead code, same function
as command flash erase_address pad 0x400 0x10

Removed "NAND" word from help as flash is obviously NOR
