Supermicro H8SCM & H8QGI: Fix printk warnings

Changes:
 - Fix printk warnings for these two platforms by getting rid of the
   l length specifier and casting to unsigned int.
   This gets rid of a bunch of warnings like this one:
     agesawrapper.c:279, GNU Compiler 4 (gcc), Priority: Normal
     format '%lu' expects argument of type 'long unsigned int',
       but argument 3 has type 'UINT32' [-Wformat]

Notes:
 - This is the same change that was done for Tyan s8226 in change:
   ddff32eb - http://review.coreboot.org/#/c/2451/
   Tyan S8226: Fix printk warnings

 - I have not tested this change on either of these platforms, I have
   just compiled it.
