Current usage information for loads command is too verbose and long for a command usage prompt. This flag simplifies the text for readability purposes.

The authentication and encryption flag naming is redundant with the description notes included. Use authflag and encflag names for the command pattern and use description lines for explanation.
New output looks like this: loads [dev] [address] [size] [authflag] [encflag] [Userkey address] Load device from memory buffer with secure bistream (authenticated/encrypted/both)(Xilinx only) -authflag: 0 for OCM, 1 for DDR, 2 for no authentication (specifies where to perform authentication) -encflag: 0 for device key, 1 for user key, 2 for no encryption -Userkey address: specifies the address where user key is stored when user key is selected NOTE: the secure bitstream has to be created using Xilinx bootgen tool only.
