From: Fabio Estevam <festevam@xxxxxxx>
The JPEG decoder/encoder present in iMX8QXP and iMX8QM SoCs need
the PER and IPG clocks to be functional, so add the clock entries.
This also fixes the following schema warning:
imx8qm-apalis-eval.dtb: jpegdec@58400000: 'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/media/nxp,imx8-jpeg.yaml#

Changes since v5:
- Remove one extra ":" from subject (thanks Fabio!)
- Use <festevam@xxxxxxx> address for both Author and Signed-of (Fabio's feedback)
Changes since v4:
- Remove redundant description and update subject prefix (per Krzysztof's feddback)
Changes since v3:
- Add items for clocks (per Krzysztof's feddback)
- Add description for clocks (per Conor's feddback to the other similar patch from Alexander)
- Add "media:" to the subject
- Add Mirela's signed-off
- For the similar patches that were sent for this issue, should Co-developed-by/Signed-off-by be added? Alexander Stein? Frank Li?
Changes since v2:
- Remove clock-names. (Mirela)
