====================
net: phy: split the mscc driver

This is a proposal to split the MSCC PHY driver, as its code base grew a
lot lately (it's already 3800+ lines). It also supports features
requiring a lot of code (MACsec), which would gain in being split from
the driver core, for readability and maintenance. This is also done as
other features should be coming later, which will also need lots of code
addition.

This series shouldn't change the way the driver works.

I checked, and there were no patch pending on this driver. This change
was done on top of all the modifications done on this driver in net-next.

Since v2:
  - Defined inline functions as static inline.
  - Fixed a locking issue reported by Kbuild.

Since v1:
  - Moved more definitions into the mscc_macsec.h header.
