timer: inherit ModuleDoc
...
With the new ModuleDoc class, we can inherit `ModuleDoc` and
automatically get module-level documentation.
This patch also corrects a typo in `timer` that causes an error in
sphinx.

integration: add ModuleDoc and AutoDoc
...
It is important to be able to document modules other than CSRs.
This patch adds ModuleDoc and AutoDoc, both of which can be used
together to document modules.
ModuleDoc can be used to transform the __doc__ string of a class into a
reference-manual section. Alternately, it can be used to add additional
sections to a module.
AutoDoc is used to gather all submodule ModuleDoc objects in order to
traverse the tree of documentation.

region if mor1kx is used with EthernetSoC. Increase the integrated ROM
size from 0x8000 to 0x10000 in EthernetSoC.

csr_eventmanager: add `name` and `description` args
...
Add `name` and `description` as optional arguments to the various
EventSource types. These default to `None`, so this should be a
backwards-compatible change.
Use the same trick as CSRs, where we default the `name` to be the
instantiated object name as read from the Migen `get_obj_var_name()`
call.
