imx: imximage: add new CHECK/CLR BIT command
* Extend imximage DCD version 2 to support DCD commands
CMD_WRITE_CLR_BIT 4 [address] [mask bit] means:
while ((*address & ~mask) != 0);
CMD_CHECK_BITS_SET 4 [address] [mask bit] means:
while ((*address & mask) != mask);
CMD_CHECK_BITS_CLR 4 [address] [mask bit] means:
*address = *address & ~mask;
* Add set_dcd_param_v2 helper function to set DCD
command parameters
