csi2_reva: Incorrect line count in end of frame detection in void MXC_CSI2_RevA_DMA_Handler()

[aniktash]

The line_cnt starts from 0, the condition should be >=, not >:
The frame complete comes late as the condition is not met after the last line is received.
This does not affect the one-shot capture, but when testing with a free-running camera, this causes an issue.

void MXC_CSI2_RevA_DMA_Handler()
{
...
// if (line_cnt > csi2_state.req-> lines_per_frame) {
**if (line_cnt >= csi2_state.req-> lines_per_frame) { **
