rockchip/rk3399: display: Retry edp initialization if it fails

We found that sometimes the edp doesn't get the edid or that video
    config fails on kevin after a reboot. Now we will retry 3 times to
    initialize it if there are errors.

BRANCH=gru
    BUG=chrome-os-partner:60150
    TEST=reboot kevin, the edp initialization error is no longer seen.
