[forcedeth] Replace driver with native iPXE driver

This patch adds a native iPXE forcedeth driver and removes the legacy
Etherboot forcedeth driver. It supports 40 different chips, compared
to the original 14.

It has been tested on a NIC with an CK804 Ethernet Controller, and the
results of downloading 5 100mb images in a row have been:
12/11/11/11/11 seconds; booting DSL using pxelinux also succeeded. The
driver has also been tested by chaining undionly.kpxe and it worked.
