kernel: Fix drm dependency on drm_panel_orientation_quirks.ko for 4.19

Package kmod-drm is missing dependencies for the following libraries:

 drm_panel_orientation_quirks.ko

It seems, that since Linux 4.15-rc2 drm depends on drm_panel_orientation_quirks.ko

    drm: Add support for a panel-orientation connector property, v6

    On some devices the LCD panel is mounted in the casing in such a way that
    the up/top side of the panel does not match with the top side of the
    device (e.g. it is mounted upside-down).

    This commit adds the necessary infra for lcd-panel drm_connector-s to
    have a "panel orientation" property to communicate how the panel is
    orientated vs the casing.

    Userspace can use this property to check for non-normal orientation and
    then adjust the displayed image accordingly by rotating it to compensate.
