[U-Boot] [PATCH] rmobile: kzm9g: Fix warnin in cmp_loop function

[Nobuhiro Iwamatsu]

cmp_loop function was used from the structure of register.
And for the member of this structure, volatile is defined.
Since a volatile declaration of cmp_loop function is not made
by argument, made warning by compiler. This fixes this problem.
