dt-bindings: mfd: bd71815: Fix rsense and typos

Browse Source 
[ 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.

BD71827 and BD71828 have SAR ADC for measuring charging currents.
External sense resistor (RSENSE in data sheet) should be used. If
something other but 30MOhm resistor is used the resistance value
should be given here in Ohms.
