wishbone2csr: refactor using FSM, reduce latency (make it asynchronous) and set csr.adr only when access is done (allow use of CSR/CSRBase we signal)
...
Making it asynchronous does not seem to deteriorate timing or resource usage, if it's the case for some designs, we'll add a register parameter.

csr: add we signal to CSR, CSRStatus
...
Doing actions on register read is generally not a good design practice (it's
better to do separate register write to trigger actions) but in some very
specific cases being able to know that register has been read can solve cases
that are difficult to do with the recommended practives and that can justify
doing an exception.
This commit add a we signal to CSR, CSRStatus and this allow the logic to know
when the CSR, CSRStatus is read.

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.
