[RFC PATCH v2 0/2] net::phy support for C45

[FUJITA Tomonori <fujita.tomonori@gmail.com>]

Adds support for reading/writing C45 registers and genphy helper
functions executed via C45 registers.

We could add methods for C45 like read/write_c45 and
genphy_c45_read_status. Instead, this implements the API for C22 and
C45 with trait in an unified way.

v2:
- add genphy helper support and split the patch
- create a 'reg' module
- define C22 according to the specs
- handle C22 vendor specific registers
- add const for C45 MMD
