deree-de5000: prepare to add more ES51919 based LCR meters 

The "deree-de5000" driver is a very thin wrapper around the ES51919
chipset. We expect more models from other vendors to use that same
support code.

Model the registration of vendor/model combinations after the serial-dmm
approach. Register the DER EE DE-5000 device as the currently only
member in a list of drivers which all use the ES51919 chipset (no model
specific routines are registered in the absence of support for other LCR
meter chips).

This commit does not change the driver's behaviour nor the set of
supported hardware. It prepares the addition of more drivers in the
future.
