eve: Check physical battery presence before inhibiting power
In order to satisfy factory testing requirements we need to
boot a bare board with just an AC adapter without requiring
a power button.
However we also don't want to always allow booting of the
battery is present but cut-off (which will indicate BP_NO so
we can't use the existing battery_is_present function) or has
critically low level as it may not immediately boot.
To accomplish this add a function that allows the board to
specify a custom "hardware presence" for the battery that is
separate from the battery presence check. This could also
likely be accomplished by adding another state to "enum
battery_present" but that could alter other behavior in the
current charge state machine..
BUG=b:63957122
BRANCH=eve
TEST=manual testing on Eve to ensure a board without a battery
is allowed to power-up when power is first applied without
requiring a power button press. Also ensure that a critically
low or cut-off battery that does not try to immediately power up.
