alpha: Remove ALPHA support and supplemental files

This patch removes support for ALPHA, and correspondingly also removes
any devices, tests, supporting functions, and configurations unique to
ALPHA.

R.I.P.

A few things that are worth re-adding using something other than
ALPHA:

1) A two-system regresssion using Ethernet

2) Ruby tester regressions using NULL for the variuos Ruby protocols
