Subject: #ifdef cleanup for drivers/net/fc/iph5526.c (240-test12-pre3)

Hi.

I recently investigated an 'unused function' warning in iph5526.c. Looking
at it (both the code causing the warning and the whole driver) convinced
me that the driver cannot be used without PCI enabled.

I therefore propose that we add a dependency in net/Config.in for this
driver and clean the driver itself of #ifdef CONFIG_PCI stuff. The patch
below does this and additionally some trivial code reordering to elininate
some further #ifdefs.

Please comment.
