dt-bindings: net: broadcom-bluetooth: Add VBAT and VDDIO supplies
The Broadcom Bluetooth chips have two power inputs, VBAT and VDDIO. The former provides overall power for the chip, while the latter powers the I/O pins and buffers. This patch adds properties for the two so we can describe the power supply relationships.
