Use struct type instead of raw array for raw profile header (NFC)

This patch introduces a well defined header struct
to represent raw profile header instead of using raw array.
Previously the raw array is used in two different files and
is very error prone when header structure is re-organized.
This is a small cleanup with NFC.
