The only usage of vsc8584_macsec_ops is to assign its address to the
macsec_ops field in the phydev struct, which is a const pointer. Make it
const to allow the compiler to put it in read-only memory.

Minor overlapping changes in xfrm_device.c, between the double
ESP trailing bug fix setting the XFRM_INIT flag and the changes
in net-next preparing for bonding encryption support.

This patch fixes the following sparse warnings when building MACsec
support in the MSCC PHY driver.
mscc_macsec.c:393:42: warning: cast from restricted sci_t
mscc_macsec.c:395:42: warning: restricted sci_t degrades to integer
mscc_macsec.c:402:42: warning: restricted __be16 degrades to integer
mscc_macsec.c:608:34: warning: cast from restricted sci_t
mscc_macsec.c:610:34: warning: restricted sci_t degrades to integer

The skcipher API dynamically instantiates the transformation object
on request that implements the requested algorithm optimally on the
given platform. This notion of optimality only matters for cases like
bulk network or disk encryption, where performance can be a bottleneck,
or in cases where the algorithm itself is not known at compile time.
In the mscc case, we are dealing with AES encryption of a single
block, and so neither concern applies, and we are better off using
the AES library interface, which is lightweight and safe for this
kind of use.
Note that the scatterlist API does not permit references to buffers
that are located on the stack, so the existing code is incorrect in
any case, but avoiding the skcipher and scatterlist APIs entirely is
the most straight-forward approach to fixing this.

This patch takes in account the use of the 1588 block in the MACsec
initialization, as a conditional configuration has to be done (when the
1588 block is used).

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.

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.
