From: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com>

In preparation for switching to a standard sizeof_member() macro to find the
size of a member of a struct, remove the custom SIZEOF_FIELD() macro and use
the more common FIELD_SIZEOF() instead. Later patches will globally replace
FIELD_SIZEOF() and sizeof_field() with the more accurate sizeof_member().
