octeontx2-pcicons: wait longer for the buffer

commit 6baec1d54245f350270761bc6ec4e4511ce0a1fd from
git@git.assembla.com:cavium/WindRiver.linux.git

Increase the timeout for waiting for the host to provide the buffer
space for the console driver from 1 ms to 2 ms. This change makes
the `Timeout awaiting host` error not appear when large output
is sent to the console.
