Add PAC1934 support in order to monitor the board power consumption.
Device is connected on flexcom7 in twi mode.
[root@SAM9X75 ~]$ awk -f pac1934.awk
VDD3V3 current: 10.675 mA, voltage: 3295.41 mV
VDDOUT4 current: 5.7625 mA, voltage: 1196.78 mV
VDDCORE current: 115.442 mA, voltage: 1243.65 mV
VDDIODDR current: 29.585 mA, voltage: 1345.21 mV
