bluetooth: hci_bcm: Give more time to come out of reset
Some supported devices need more time to come out of reset (eg. BCM4345C5 in AP6256). I don't have/found a datasheet, so the value was arrive at experimentally with the Oprange Pi 3 board. Without increased delay, I got intermittent failures during probe. This is a Bluetooth 5.0 device, so maybe that's why it takes longer to initialize than the others.
