Switch_ON(): detect charging mode by CHGPRES bit
Consider the following scenario: the phone is on, the user plugs in
the charger, and then executes the power-off operation. In the Iota
VRPC this sequence translates to a switch-off immediately followed
by another switch-on - but the CHGSTS bit doesn't get set on the second
switch-on cycle! Disassembly of Pirelli's fw shows that they check
the CHGPRES bit, and furthermore, if both CHGPRES and ONBSTS are set,
the code they pass to their modified Power_ON_Button() function is
the one for charging - so let's adopt the same CHGPRES check and
the same priority order for switch-on causes.
