Since the Felix DSA driver is implementing its own PHYLINK instance due
to SoC differences, it needs access to the few registers that are
common, mainly for flow control.

The Ocelot switchdev driver and the Felix DSA one need it for different
reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is
integrated with the traditional NXP Layerscape PCS design which does not
support runtime configuration of SerDes protocol. So it needs to
pre-validate the phy-mode from the device tree and prevent PHYLINK from
attempting to change it. For this, it needs to cache it in a private
variable.

Convert to use skb queue instead of the list of skbs.
The skb queue could provide protection with lock.

Convert to use ocelot_port_add_txtstamp_skb() for adding skbs which
require TX timestamp into list. Export it so that DSA Felix driver
could reuse it too.

The method getting TX timestamp by reading timestamp FIFO and
matching skbs list is common for DSA Felix driver too.
So move code out of ocelot_board.c, convert to use
ocelot_get_txtstamp() function and export it.

The Felix DSA driver needs to write to SYS_RAM_INIT_RAM_INIT for its own
chip initialization process.
Also update the MAINTAINERS file such that the headers exported by the
ocelot driver are under the same maintainers' umbrella as the driver
itself.

We will be registering another switch driver based on ocelot, which
lives under drivers/net/dsa.
Make sure the Felix DSA front-end has the necessary abstractions to
implement a new Ocelot driver instantiation. This includes the function
prototypes for implementing DSA callbacks.

Since HSIO address space can be accessed by different drivers, let's
simplify the register address definitions so that it can be easily used
by all drivers and put the register address definition in the
include/soc/mscc/ocelot_hsio.h header file.

Since HSIO address space can be used by different drivers (PLL, SerDes
muxing, temperature sensor), let's move it somewhere it can be included
by all drivers.
