dt-bindings: mfd: bd71828: Use charger resistor in mOhm instead of MOhm 



Apparently there was some confusion regarding milliohm vs. megaohm.
(m/M). Use microohms to be able to properly specify the charger
resistor like other drivers do. This is not used yet by mainline code
yet. Specify a current sense resistor in milliohms range rather then
megaohms range in the examples.

      BD71827 and BD71828 have SAR ADC for measuring charging currents.

      External sense resistor (RSENSE in data sheet) should be used. If some

      other but 30MOhm resistor is used the resistance value should be given

      here in Ohms.
