LibDeviceTree: Add functions for getting and translating addresses
...
I created this test file by running the following command:
dtc -o address-translation.dtb <<EOF
/dts-v1/;
/ {
compatible = "serenity,address-translation-test";
#address-cells = <2>;
#size-cells = <1>;
soc {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0xa0000000 0xfe 0xd0000000 0x40000000>;
usb@a0010000 {
reg = <0xa0010000 0x100000>;
};
some-bus@b0000000 {
compatible = "simple-bus";
#address-cells = <2>;
#size-cells = <2>;
ranges = <0x02 0x00 0xb0000000 0x00 0x200000>;
leds@200100000 {
reg = <0x02 0x100000 0x00 0x1000>;
};
};
};
};

LibDeviceTree: Rename DeviceTreeNodeView to Node
...
The class is in the DeviceTree namespace, so the prefix is redundant.
Calling it a 'View' is also somewhat misleading, as it is not simply a
cheap-to-copy reference to the underlying memory but is instead marked
as AK_MAKE_NONCOPYABLE.

LibDeviceTree: Fix stale pointers in phandle and parent handling
...
We need to set them after we've created the full tree, as otherwise the
HashMap containing the nodes may reallocate and invalidate the pointers.

LibDeviceTree: Add a simple DeviceTree class
...
This makes it easier to work with device tree nodes and properties, then
writing simple state machines to parse the device tree.
This also makes the old slow traversal methods use the
DeviceTreeProperty helper class, and adds a simple test.
