Help description for both options only tells users to enable them
without description of what VME bridge and TSI148 device are.
Briefly describe them.

This is a wording alternative to Dorine's patch [1]. The wording is
inspired by [2] and [3].

- If you say Y here you get support for the VME bridge Framework.
+ Enable support for VME (VersaModular Eurocard bus) bridge modules.
+ The bridge allows connecting VME devices to systems with existing
+ interfaces (like USB or PCI) by means of translating VME protocol
+ operations.
+
+ Note that this only enables the bridge framework. You'll also
+ likely want to enable driver for specific bridge device you have
+ to actually use it. If unsure, say N.
