This is a general method for setting any of the structure's attributes
(callbacks and data fields).  I'm open to suggestions for a better name,
but 'callback' isn't it.

I started out going down that path, but quickly realized that it was
better to augment the API rather than refactoring it.  Here's why
(please look past my horrid shell skills):

saruman$ cd u-boot
saruman$ grep -R miiphy_read * | sed s/:/\ / | awk '{print $1}' | uniq |
wc -l
33
saruman$ grep -R miiphy_write * | sed s/:/\ / | awk '{print $1}' | uniq
| wc -l
40
saruman$ grep -R miiphy_register * | sed s/:/\ / | awk '{print $1}' |
uniq | wc -l
18

The 'struct mii_dev' definition currently has private scope within
'miiphy_util.c'.  I guess we could put it in a header file and add
another register function that takes a struct as argument.  What is it
about the current implementation that doesn't meet your needs, though?
