hdata: Fix vpd parse

We detect vpd data format in vpd_parse() and set "op_platform" variable.
dt_add_vpd_node() depends on op_platform to select parser type.

There are places where we call dt_add_vpd_node() even before calling
vpd_parse(). And in such cases it will not parse vpd data properly.

This patch fixes above issue.
