Right now, we include a few panics and assertions in the code that
generates AML bytecode for our ACPI tables.

Change the AML methods to explicitly return a Result type and substitute
these panics and assertions with error types. Also, change some type
methods that now need to return a Result as well.

We were calling stuff "Cachable" instead of "Cacheable".

acpi_tables::aml::AddressSpace<T> type is describing an address space
with a minimum address `min: T` and a maximum address `max: T`.
Currently, we do not perform any checks on these values when creating
the AddressSpace objects. This means that the starting address `min` can
be bigger than the last address `max`, which can cause underflows when
calculating the length of this address space, i.e. `max - min + 1`.

Add a check in the constructor methods of AddressSpace objects and
return an error when `min > max`.
