Below is what I was trying. I put this toward the end of shamcop_probe, but 
you could just as easily stick it in h2200.c for now.

#if 1
        /* GPIO_NR_H2200_BT_IDENT and
           GPIO_NR_H2200_BT_IRQ are inputs */

        SET_H2200_GPIO(BT_RESET_N, 0);

        CKEN |= CKEN7_BTUART;

        /* select normal operation */
        SET_H2200_GPIO(BT_WAKE, 0);

        /* apply power */
        SET_H2200_GPIO(BT_POWER_ON, 1);

        SET_H2200_GPIO(BT_RESET_N, 1);

#endif
