Several Qualcomm Bluetooth controllers lack persistent storage for the
device address and instead one can be provided by the boot firmware
using the 'local-bd-address' devicetree property.
The Bluetooth bindings clearly states that the address should be
specified in little-endian order, but due to a long-standing bug in the
Qualcomm driver which reversed the address some boot firmware has been
providing the address in big-endian order instead.
The only device out there that should be affected by this is the WCN3991
used in some Chromebooks.
Add a 'qcom,local-bd-address-broken' property which can be set on these
platforms to indicate that the boot firmware is using the wrong byte
order.
Note that ChromeOS always updates the kernel and devicetree in lockstep
so that there is no need to handle backwards compatibility with older
devicetrees.

Pull devicetree updates from Rob Herring:
"Bindings:
- Add some missing type definitions to properties
- Drop unneeded quotes and use absolute paths in bindings
- Remove redundant "binding" or "schema" in binding titles
- Add bindings for Ralink SoCs interrupt controller, QCA2066
Bluetooth, infineon,irps5401, new NXP i.MX GPT variants, shineworld
lh133k MIPI SPI panel, Socionext Synquacer platforms, RK3588 PCIe,
ST M95640 EEPROM, and FSL DCP crypto variants, and Arm Cortex-R52
DT core:
- Improve the reserved-memory range allocation to maximize contiguous
space
- Use device_set_node() helper in place of open coding"

Bluetooth controllers share the common local-bd-address property.
Add a generic YAML schema to replace bluetooth.txt for those.
