[ Upstream commit 177d841fa19542eb35aa5ec9579c4abb989c9255 ]

Commit 1f82f2df523cb ("media: hantro: Enable H.264 on Rockchip VDPU2")
enabled H.264 on some SoCs with VDPU2 cores. This had the side-effect
of exposing H.264 coded format as supported on RK3399.

Fix this and clarify how the codec is explicitly disabled on RK3399 on
this driver.
