[PATCH 2/7] media: rkvdec: Add support for the VDPU346 variant

[Daniel Golle <daniel@makrotopia.org>]

From: Christian Hewitt <christianshewitt@gmail.com>

VDPU346 is similar to VDPU381 but with a single core and limited
to 4K60 media. It is also limited to H264 L5.1 and omits AV1 and
AVS2 capabilities. VDPU346 is used with RK3566 and RK3568.
