staging: comedi: plx9080.h: remove Power-Up Test Suite stuff 



The defines related to the Power-Up Test Suite (PUTS) are just cruft that
has nothing to do with the PLX PCI-9080 chip.  They seem to have been
inherited from "drivers/net/plx9060.h" in the kernel 2.2.16 sources for
use by the "wanxl" driver.  Remove them.

/*

 * The PCI Interface, via the PCI-9060 Chip, has up to eight (8) Mailbox

 * Registers.  The PUTS (Power-Up Test Suite) handles the board-side

 * interface/interaction using the first 4 registers.  Specifications for

 * the use of the full PUTS' command and status interface is contained

 * within a separate SBE PUTS Manual.  The Host-Side Device Driver only

 * uses a subset of the full PUTS interface.
