From: Fabio Estevam <festevam at denx.de>
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 at 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#
