Subject: [PATCHv4 1/6] firmware: stratix10-svc: add COMMAND_AUTHENTICATE_BITSTREAM flag

From: Richard Gong <richard.gong@...el.com>

Add COMMAND_AUTHENTICATE_BITSTREAM command flag for new added bitstream
authentication feature. Authenticating a bitstream is to make sure a signed
bitstream has the valid signatures.

Except for the actual configuration of the device, the bitstream
authentication works the same way as FPGA configuration does. If the
authentication passes, the signed bitstream will be programmed into QSPI
flash memory and will be expected to boot without issues.
