greybus: rename HOST_DEV_CPORT_ID_MAX

We limit the number of host-side CPorts to a fixed maximum (which
is less than the 4096 that UniPro allows).  This patch imposes a
similar limit on the CPort IDs defined by modules (signaling an
error if one too large is found in a manifest).

It seems reasonable to use the same value for both limits.  Change
the name of the constant that defines the host limit and use it for
both.  Update cport_id_valid() to enforce the maximum.

(Ultimately we should impose a limit like this; this change is being
made in preparation for supporting multiple connections over a
single CPort.)
