mb/siemens/mc_ehl5: Set LVDS re-power delay to 1 s
The currently used panel type could work with 500 ms but increasing
the value to 1 second allows to use a wider range of LVDS LCD panels,
as many of them specify the delay of 1 s as minimum.
The patch has already been made for mc_ehl3 and serves the purpose of
standardization.
