Artur Weber ac9e52aca2 power: supply: max77693: Fix wrong conversion of charge input threshold value 
[ Upstream commit 30cc7b0d0e ]

The charge input threshold voltage register on the MAX77693 PMIC accepts
four values: 0x0 for 4.3v, 0x1 for 4.7v, 0x2 for 4.8v and 0x3 for 4.9v.
Due to an oversight, the driver calculated the values for 4.7v and above
starting from 0x0, rather than from 0x1 ([(4700000 - 4700000) / 100000]
gives 0).

Add 1 to the calculation to ensure that 4.7v is converted to a register
value of 0x1 and that the other two voltages are converted correctly as
well.
