5.15-stable review patch. If anyone has any objections, please let me know.

From: Matti Vaittinen mazziesaccount@gmail.com
[ Upstream commit 6856edf7ead8c54803216a38a7b227bcb3dadff7 ]
The sense resistor used for measuring currents is typically some tens of milli Ohms. It has accidentally been documented to be tens of mega Ohms. Fix the size of this resistor and a few copy-paste errors while at it.
Drop the unsuitable 'rohm,charger-sense-resistor-ohms' property (which can't represent resistors smaller than one Ohm), and introduce a new 'rohm,charger-sense-resistor-micro-ohms' property with appropriate minimum, maximum and default values instead.
