dt-bindings: net: broadcom-bluetooth: Add conditional constraints
Add conditional constraint to make property "reset-gpios" available only
for compatible devices acually having the reset pin.
Make property "brcm,requires-autobaud-mode" depend on property
"shutdown-gpios" as the shutdown pin is required to enter autobaud mode.
I looked at all compatible devices and compiled the matrix below before
formulating the conditional constraint. This was a pure paper exercise and
no verification testing has been performed.
