[PATCH RESEND] drivers: staging: vme_user: Describe VME_BUS and VME_TSI148

[Bagas Sanjaya <bagasdotme@gmail.com>]

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].
