gianfar: Device configuration fixes

This patchset represents the first part of an effort
to solve some old device configuration issues in gianfar,
especially run-time reset and re-configuration problems.
I'm referring to "on-the-fly" configuration of registers
against HW specification, concurrency issues during device
reset / re-configuration operations, and implementing HW
advisories for these operations.

There's also a good deal of code cleanup and refactoring,
and some other (minor) fixes as well.

v2: Remove sysfs stubs w/o replacing them with module
    params (patch 2).
