mb/siemens/mc_ehl3/lcd_panel.c: 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. BUG=none TEST=Test link stability using a panel with minimum re-power delay of 1 s.
