+ * FunctionName : user_rf_cal_sector_set
+ * Description  : SDK just reversed 4 sectors, used for rf init data and paramters.
+ *                We add this function to force users to set rf cal sector, since
+ *                we don't know which sector is free in user's application.
+ *                sector map for last several sectors : ABCCC
+ *                A : rf cal
+ *                B : rf init data
+ *                C : sdk parameters
+ * Parameters   : none
+ * Returns      : rf cal sector
