MLK-19514-1: ISI: correct capture and output meaning
According to V4L2 doc, cap_q_ctx is for "output to memory" queue and out_q_ctx is for "input from memory", so capature should represent for output of ISI and output should represent for ISI's input. But I reversed their relationship, so correct it. Signed-off-by: Guoniu.Zhou <guoniu.zhou@nxp.com>
