arm64: dts: imx8mq-tqma8mq-mba8mx: Remove invalid properties

They originated from the downstream kernel and slipped into mainline.
Remove them to silence also dtbs_check warnings:
pcie@33800000: Unevaluated properties are not allowed ('epdev_on-supply',
  'hard-wired' were unexpected)
pcie@33c00000: Unevaluated properties are not allowed ('epdev_on-supply',
  'hard-wired' were unexpected)
