The driver is responsible for building a JPEG compliant bitstream and placing the entropy-encoded scan in it. Right now the driver uses a bounce buffer for the hardware to output the raw scan to. In commit e765dba11ec2 ("hantro: Move hantro_enc_buf_finish to JPEG codec_ops.done"), the code that copies the raw scan from the bounce buffer to the capture buffer was moved, but was only hooked up for the Hantro H1 (then RK3288) variant. The RK3399 variant was broken, producing a JPEG bitstream without the scan, and the capture buffer's .bytesused field unset. Fix this by duplicating the code that is executed when the JPEG encoder finishes encoding a frame. As the encoded length is read back from hardware, and the variants having different register layouts, the code is duplicated rather than shared.
