std::optional<bool> AsBool ()A value without size represents a Boolean property whose truthiness is a
function of the nature of the property's name and its presence in the tree.

std::optional<StatusProperty> AsStatus ()Returns a valid `StatusProperty` or `std::nullopt` in case the provided string does not match
any known value.

std::optional<RegProperty> AsReg (const PropertyDecoder & decoder)Given a device node's property decoder |decoder|, the property value is assumed
to be a property encoded array, to be interpreted as 'reg'.
The number of address cells and size cells are obtained from the parent, or if
not present they are assumed to be 2 for address cells or 1 for size cells.

* 'reg'

std::optional<RangesProperty> AsRanges (const PropertyDecoder & decoder)Attempts to parse the bytes a 'ranges' property. A ranges property consist of an array of
3-Tuples, the first element being the child bus address, then the parent bus address and the
length of the range last. The number of cells of each entry is obtained as follows:
* 'address-cells' for child bus address from decoder itself.
* 'address-cells' for parent bus address from decoder's parent.
* 'size-cells' for length from decoder itself.
