docs / driver-api: Fix structure references in device_link.rst

The format of the structure references in device_link.rst is
incorrect, because it doesn't cause proper references to the
struct data types to be generated (for struct dev_pm_domain in
particular).

Fix that by using the :c:type:`struct name <name>` convention
for encoding references to struct data types.

Fixes: aad80040

The fact that both devices share the same power domain would normally
suggest usage of a :c:type:`struct dev_pm_domain` or :c:type:`struct
generic_pm_domain`, however these are not independent devices that
happen to share a power switch, but rather the MMU device serves the
busmaster device and is useless without it. A device link creates a
synthetic hierarchical relationship between the devices and is thus
more apt.
