MLK-17093 imx8qm/qxp: enable control bit for RGMII interface RX clock delay

Due to RGMII interface timing requirement for imx8qm/qxp mek and arm2
board, it needs to enable RX clock delay.

It should not depend on HW default status since kernel may clear the
bit only on imx8qm/qxp platforms, then reboot test will cause uboot
networking failed.
