Driver: ISL9237: Monitor system power consumption
Added code to enable the system power monitoring functionality to get the
details of the system power consumption.
And also added EC console command "psys" to get the system power consumption.
BUG=none
TEST=Manually tested on Kunimitsu.
Power = Voltage * Current, reading is equal to the power readings
from the psys command.
BRANCH=none
