Segregate utility methods

This commit segregates utility methods required commonly by both
openpower-read-vpd and ibm-read-vpd from methods only required by
ibm-read-vpd.
All dependency required by utility methods specific to ibm-read-vpd
is not applicable to utility methods required by openpower-read-vpd.

Hence to avoid un-necessary dependency inclusion, this change is
introduced.
