Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading.
Autobaud mode can also be required on some boards where the controller
device is using a non-standard baud rate when first powered on.

Only a limited subset of HCI commands are supported in autobaud mode.

These patches add a DT property, "brcm,requires-autobaud-mode", to control
autobaud mode selection.

Changes v2 -> v3:
- Rename DT property and modify description in binding document

Changes v1 -> v2:
- Modify description in binding document
