Subject: [PATCH 09/18] arm64: dts: rk3399-pinephone-pro: Correct the battery

XLS with ZCV measurements from the manufacturer say that at 25°C,
|
|
ZCV is ~200 mOhm. At 50°C it's at ~100 mOhm. Set some value in between.
|
|
|
|
Lower the charging current to something less aggressive.
|
|
|
|
Fix the current sensing resitor value (it's 10 mOhm in the schematic).
