Subject: [PATCH v3, 09/10] media: mtk-vcodec: Add venc_multi_core mode encode process
The venc_multi_core mode encoding is tries to uses all available cores.
MT8195 has two venc cores:
frame#0 uses core#0, frame#1 uses core#1, frame#2 uses core#0...,
Lock the device and enable the clock by used core, for sequence
header encoding, it always uses core#0.
