ipod 4g/color: Fix unresponsive buttons after booting

The iPod 4g and color always ignored the very first
button press after booting, i.e. you needed to either
press another button or scroll for a bit first.

Not sure whether any other PP iPods exhibit the same
behavior, although it is not reproducible on an iPod
video.

This patch basically copies the code from FS#5230
that fixed unresponsive buttons whenever the HOLD
switch was turned off (committed as a5961c944b).
