The key length used to store the macsec key was set to MACSEC_KEYID_LEN
(16), which is an issue as:
- This was never meant to be the key length.
- The key length can be > 16.
Fix this by using MACSEC_MAX_KEY_LEN instead (the max length accepted in
uAPI).

All headers in the MSCC PHY driver have been copied and pasted from the
original mscc.c file. However the information is not necessarily
correct, as in the MACsec support. Fix this.

At the very end of the MACsec block initialization in the MSCC PHY
driver, the MACsec "protocol mode" is set. This setting should be set
based on the PHY id within the package, as the bank used to access the
register used depends on this. This was not done correctly, and only the
first bank was used leading to the two upper PHYs being unstable when
using the VSC8584. This patch fixes it.

Cosmetic commit fixing the MSCC PHY header defines and descriptions,
which were referring the to MSCC Ocelot MAC driver (see
drivers/net/ethernet/mscc/).

This patch splits the MSCC driver into separate files, per
functionality, to improve readability and maintenance as the codebase
grew a lot. The MACsec code is moved to a dedicated mscc_macsec.c file,
the mscc.c file is renamed to mscc_main.c to keep the driver binary to
be named mscc and common definition are put into a new mscc.h header.
Most of the code was just moved around, except for a few exceptions:
- Header inclusions were reworked to only keep what's needed.
- Three helpers were created in the MACsec code, to avoid #ifdef's in
the main C file: vsc8584_macsec_init, vsc8584_handle_macsec_interrupt
and vsc8584_config_macsec_intr.
The patch should not introduce any functional modification.

The MSCC PHY driver is growing, with lots of space consuming features
(firmware support, full initialization, MACsec...). It's becoming hard
to read and navigate in its source code. This patch moves the MSCC
driver to its own directory, without modifying anything, as a
preparation for splitting up its features into dedicated files.
