There's a WCN6855 WiFi/Bluetooth module on an M.2 card. To make
Bluetooth work, we need to define the necessary device tree nodes,
including UART configuration and power supplies.

Since there is no standard M.2 binding in the device tree at present,
the PMU is described using dedicated PMU nodes to represent the
internal regulators required by the module.

The 3.3V supply for the module is assumed to come directly from the
main board supply, which is 12V. To model this in the device tree, we
add a fixed 12V regulator node as the DC-IN source and connect it to
the 3.3V regulator node.
