battery: 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 CL is taking a change done for Eve and pulling into TOT so it can
be used for other projects that have the same
requirements. https://chromium-review.googlesource.com/c/582544
