[Skiboot] [PATCH] gard: fix compile error on ARM

[Cédric Le Goater]

gard can be used on the BMC to query garded records, but currently
compile fails with :

  cc -O2 -Wall -Werror -I. -c gard.c -o gard.o
  gard.c: In function 'do_clear_i':
  gard.c:421:12: error: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'size_t' [-Werror=format]
  gard.c: In function 'check_gard_partition':
  gard.c:489:36: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'unsigned int' [-Werror=format]

This patches provides a fix compatible with x86, armel, ppc64.
