latona: power: don't detect full charge with CHG_ING GPIO

CHG_ING is high when the battery is fully charged, but we
may want to stop charging before that.
Fix also the recharging conditions to prevent too frequent
battery recharges which were previously limited by CHG_ING.
latona: power: set low SOC alert threshold properly
drivers: max17040: use adjusted soc values only for uevents
omapfb: allow to show a progress bar on boot
omapfb: progressbar: tweak for latona

Make the progressbar faster when booting to recovery and don't show
it at all when booting to charging mode.
defconfig: show progressbar on boot
