[PATCH v11] arm64: dts: imx8qxp: Add jpeg encoder/decoder nodes

[Aisheng Dong]

> Add dts for imaging subsytem, include jpeg nodes here.
> Tested on imx8qxp only, should work on imx8qm, but it was not tested.

> Changes in v11:
>   Adress feedback from Aisheng Dong:
>   - Rename img_jpeg_dec_clk/img_jpeg_enc_clk to
> jpeg_dec_lpcg/jpeg_enc_lpcg to make it visible it's lpcg not other type of clk
>   - Drop the cameradev node, not needed for jpeg
>   - Match assigned-clocks & assigned-clock-rates

Pls fix LPCG index by using clock indice
