[dpdk-web] fix ecosystem URLs

[Thomas Monjalon]

Hi,

Some links are wrong in the page http://www.dpdk.org/ecosystem/#hardware

Please fix links for mlx4 and mlx5.
In order to avoid using redirections, you could change all doc links
from http://www.dpdk.org/doc/* to http://doc.dpdk.org/*

There were also a private request from Cavium to change
	thunderx (CN88XX, CN83XX, CN81XX, CN80XX)
	octeontx (CN83XX)
to
	thunderx (CN88XX)
	octeontx (CN83XX, CN82XX, CN81XX, CN80XX)
as it is done in http://core.dpdk.org/supported/nics/cavium/

You can also remove the Attic corner on this page.

Thank you
