USB: use MII hooks only if CONFIG_MII is enabled
Fix mcs7830 patch
The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:
- it made the usbnet infrastructure reference MII symbols even
when they're not needed in the kernel being built
- it didn't enable MII along with the mcs7830 minidriver
This patch fixes these two problems.
However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too. So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.
