NICs uses different delays up to a second during their
configuration. It makes no sense to busy-wait so long wasting
CPU cycles and preventing any other threads to execute on the
same CPU core. These busy polling are the rudiments that came
from the kernel drivers where you can not sleep in interrupt
context, but as we're in userspace, we're able and should
sleep to allow other threads to run.
Delays never called on rx/tx path, so this should not affect
performance.

This commit fixes a compilation error if EM_PMD is
not defined, bug IGB_PMD is. The root cause of the
issue was that log init variables are declared as
extern in a header file, while the definition of the
variables was in e1000_ethdev.c. Hence, the definitions
were not available if the e1000 PMD is disabled.
To fix this, a new file is added e1000_logs.c, which
matches the e1000_logs.h header. The log variables are
always compiled in, but the PMD logs are only registered
if a PMD is enabled in the configuration. Extra checks
are added in order to avoid duplicate registering.
