Subject: [PATCH] arm64: dts: mt8173: fix vcodec-enc clock
Fix the assigned-clock-parents to higher frequency clock to avoid h264
encode timeout:
[ 134.763465] mtk_vpu 10020000.vpu: vpu ipi 4 ack time out !
[ 134.769008] [MTK_VCODEC][ERROR][18]: vpu_enc_send_msg() vpu_ipi_send msg_id c002 len 32 fail -5
[ 134.777707] [MTK_VCODEC][ERROR][18]: vpu_enc_encode() AP_IPIMSG_ENC_ENCODE 0 fail
venc_sel is the clock used by h264 encoder, and venclt_sel is the clock
used by vp8 encoder. Assign venc_sel to vcodecpll_ck and venclt_sel to
vcodecpll_370p5.
vcodecpll 1482000000
vcodecpll_ck 494000000
venc_sel 494000000
...
vcodecpll_370p5 370500000
venclt_sel 370500000
