Subject: [PATCH v3 11/12] staging: gpib: Re-order the lookup tables

Re-order the tables so that the bcm27xx table is used first
as these devices are more popular and numerous than the older ones.
This is slightly more efficient for the later pi3 and subsequent models
but should not be noticable in practice for all users.
