tg3: Remove unused cfgspc device members
This patch removes the pci_bist and pci_hdr_type members from the
device structure and removes the code that references them. They are
not really used.
The patch rounds out the changes by moving the pci_cmd member to plug
a structure hole that would have been created. On 32-bit systems, this
movement removes a subsequent structure hole later in the structure. On
64-bit systems though, the movement merely consolidates two holes into
one larger hole.
