PS6: 
Suggestion for a more human speak implementation:

```
// turn the readio on
void mec5035_radio_on(enum mec5035_radio_dev dev)
{
    /* From LPC traces and userspace testing with other values,
       the second byte has to be 2 for an unknown reason. */
    u8 buf[3] = {dev, 2, RADIO_ON};
    write_mailbox_regs(buf, 2, 3);
    ec_command(CMD_SET_RADIO);
}

// turn the readio off
void mec5035_radio_off(enum mec5035_radio_dev dev)
{
    /* From LPC traces and userspace testing with other values,
       the second byte has to be 2 for an unknown reason. */
    u8 buf[3] = {dev, 2, RADIO_OFF};
    write_mailbox_regs(buf, 2, 3);
    ec_command(CMD_SET_RADIO);
}
```
