Subject: [PATCH] staging: silicom: hide conditionally used function in condition

bp_proc_create() be called only when BP_PROC_SUPPORT defined but its
definition live outside of #ifdef BP_PROC_SUPPORT and cause following
trivial build warning:
drivers/staging/silicom/bpctl_mod.c:6786:12: warning:
‘bp_proc_create’ defined but not used [-Wunused-function]
 static int bp_proc_create(void)
            ^

Fix the warning by hide the definition inside #ifdef BP_PROC_SUPPORT.
