ENGR00216946: battery: increase update period to 2 minutes
increase update period to 2 minutes. Due to improper hardware design,
when enable HDCP function, the I2C2 bus pins function is change to DDC
function,the CPU loading is high when I2C failed transfer data via I2C
bus,so decrease battery update voltage frequency.
