media: coda: avoid hardware lockups with more than 13 capture buffers
When decoding using the CODA internal rotator (for example NV12
capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19)
is written into the DEC_PIC_ROT_INDEX register. At least with firmware
version 3.1.1 this causes CODA hangups as soon as the register value
reaches 32. Instead, always write CODA_MAX_FRAMEBUFFERS.
