arm64: dts: mt8173: fix vcodec-enc clock

Browse Source 
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
