KeyguardRotateController handles minimum show time

Instead of KeyguardIndicationTextView ensuring that
keyguard messages are shown for a minimum amount of time,
move logic into KeygaurdIndicationRotateTextViewController,
since the rotating text view controller already handles
the rotating text durations its easier to coordinate
the timing in one class rather than across two.

Update the charging info if the device is at full charged and
is plugged in. Sometimes the battery status is not updated
so we need  to check the actual %.
