Subject: [PATCH v3 1/2] media: dt-binding: media: Document rk3588’s VEPU121

This encoder-only device is present four times on this SoC, and should
support everything the rk3568 vepu supports (so JPEG, H.264 and VP8
encoding).

According to the TRM[1], there is also the VEPU580 encoder which
supports H.264 and H.265, and various VDPU* decoders, of which only the
VDPU981 is currently supported.  This patch describes only the VEPU121.
