dt: add helper for phandle allocation
Phandle references work by having 2 pieces:
- a "phandle" 1-cell property in the device tree node
- a reference to the same value in a property we want to point
to the other node
To generate the 1-cell property, we need an allocation mechanism that
gives us a unique number space. This patch adds an allocator for these
properties.
