EM/Battery: Moving battery characterization data into board file for clovertrail

BZ: 30263

This patch is submitted to move the battery characterization data into board
file. Since there is a dependency on SMIP to provide this data, moving data
temporarily. Once the SMIP provides the battery characterization data, the
driver will read the data from SMIP only.
