jedec_ts: add many more devices from various vendors
The new IDs are taken from the hardware to which I have access and from open datasheets. Also, the hardware probing is moved to the device probe method. Reviewed by: rpokala MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D11730

* General device identification notes.
|

*
|
||||
* The JEDEC TSE2004av specification defines the device ID that all compliant
|
||||
* devices should use, but very few do in practice. Maybe that's because
|
||||
* TSE2002av was rather vague about that.
|
||||
* Rare examples are IDT TSE2004GB2B0 and Atmel AT30TSE004A, not sure if
|
||||
* they are TSE2004av compliant by design or by accident.
|
||||
* Also, the specification mandates that PCI SIG manufacturer IDs are to be
|
||||
* used, but in practice the JEDEC manufacturer IDs are often used.
