integration/builder: When the CPU is "None", we used to not generate any code.
...
With this change, we will now generate csr.h and sdram_phy.h, which
will be needed by the initialization code running on the host CPU.

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.
