Subject: [PATCH 1/1] dt-bindings: media: imx-jpeg: add clocks,clock-names,slot to fix warning

Fix below DTB_CHECK warning.

make CHECK_DTBS=y freescale/imx8qxp-mek.dtb
  DTC_CHK arch/arm64/boot/dts/freescale/imx8qxp-mek.dtb
arch/arm64/boot/dts/freescale/imx8qxp-mek.dtb: jpegdec@...00000: 'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'clocks', 'slot' do not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/media/nxp,imx8-jpeg.yaml#

Add 'clocks' and 'clock-names' property.
Add 'slot' to choose which physical jpeg slot.
