Subject: bluetooth: hci_bcm: Give more time to come out of reset
Git-commit: 16946de5905fff243c1e4415c4565803945e8c47
Patch-mainline: v5.4-rc1
References: jsc#SLE-7772
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.
