Phone boot with PWON: weed out short button presses
Every standard end user phone has a design provision, most naturally
implemented in firmware, whereby the PWON button effects a boot only
if it is held down long enough - short presses of this PWON button
are detected, assumed to be spurious and cause the fw to power back off
instead of proceeding with boot. The present change introduces this
standard function in FreeCalypso.
