power: supply: cpcap-battery: Fix signed counter sample register
[ Upstream commit c68b901ac4fa969db8917b6a9f9b40524a690d20 ]
The accumulator sample register is signed 32-bits wide register on
droid 4. And only the earlier version of cpcap has a signed 24-bits
wide register. We're currently passing it around as unsigned, so
let's fix that and use sign_extend32() for the earlier revision.
