fbdev: modedb: Fix misaligned fields in the 1920x1080-60 mode
The 1920x1080@60 modedb entry has one too many initializers before its sync field: a stray "0" occupies the sync slot, which shifts the remaining values by one field. The entry therefore decodes as sync = 0, vmode = FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT (0x3, i.e. FB_VMODE_INTERLACED | FB_VMODE_DOUBLE), and flag = FB_VMODE_NONINTERLACED, instead of the intended sync = positive H/V, vmode = non-interlaced. fb_find_mode() then returns a 1920x1080 mode flagged as interlaced + doublescan with active-low syncs. Drivers that honour var->vmode and var->sync when programming display timing enable doublescan and the wrong sync polarity, corrupting the output. Drop the stray initializer so sync and vmode hold their intended values (positive H/V sync, non-interlaced), matching the adjacent 1920x1200 entry.
