SJA1105 DSA driver preparation for new switch introduction (SJA1110)

This series contains refactoring patches which are necessary before the
support for the new NXP SJA1110 switch can be introduced in this driver.

As far as this series is concerned, here is the list of major changes
introduced with the SJA1110:
- 11 ports vs 5
- port 0 goes to the internal microcontroller, so it is unused as far as
  DSA is concerned
- the Clock Generation Unit does not need any configuration for
  setting up the PLLs for MII/RMII/RGMII
- the L2 Policing Table contains multicast policers too, not just
  broadcast and per-traffic class. These must be minimally initialized.
- more frame buffers
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The shared frame buffer of the SJA1110 is larger than that of SJA1105,
which is natural due to the fact that there are more ports.

Introduce yet another property in struct sja1105_info which encodes the
maximum number of 128 byte blocks that can be used for frame buffers.

The SJA1110 policer array is similar in layout with SJA1105, except it
contains one multicast policer per port at the end.

Detect the presence of multicast policers based on the maximum number of
supported L2 Policing Table entries, and make those policers have a
shared index equal to the port's default policer. Letting the user
configure these policers is not supported at the moment.

Due to the fact that the port count is different, some static config
tables have a different number of elements in SJA1105 compared to
SJA1110. Such an example is the L2 Policing table, which has 45 entries
in SJA1105 (one per port x traffic class, and one broadcast policer per
port) and 110 entries in SJA1110 (one per port x traffic class, one
broadcast and one multicast policer per port).

Similarly, the MAC Configuration Table, the L2 Forwarding table, all
have a different number of elements simply because the port count is
different, and although this can be accounted for by looking at
ds->ports, the policing table can't because of the presence of the extra
multicast policers.

The common denominator for the static config initializers for these
tables is that they must set up all the entries within that table.
So the simplest way to account for these differences in a uniform manner
is to look at struct sja1105_table_ops::max_entry_count. For the sake of
uniformity, this patch makes that change also for tables whose number of
elements did not change in SJA1110, like the xMII Mode Parameters, the
L2 Lookup Parameters, General Parameters, AVB Parameters (all of these
are singleton tables with a single entry).

There are two distinct code paths which enter sja1105_clocking.c, one
through sja1105_clocking_setup() and the other through
sja1105_clocking_setup_port():

sja1105_static_config_reload      sja1105_setup
              |                         |
              |      +------------------+
              |      |
              v      v
   sja1105_clocking_setup               sja1105_adjust_port_config
                 |                                   |
                 v                                   |
      sja1105_clocking_setup_port <------------------+

As opposed to SJA1105, the SJA1110 does not need any configuration of
the Clock Generation Unit in order for xMII ports to work. Just RGMII
internal delays need to be configured, and that is done inside
sja1105_clocking_setup_port for the RGMII ports.

So this patch introduces the concept of a "reserved address", which the
CGU configuration functions from sja1105_clocking.c must check before
proceeding to do anything. The SJA1110 will have reserved addresses for
the CGU PLLs for MII/RMII/RGMII.

Additionally, make sja1105_clocking_setup() a function pointer so it can
be overridden by the SJA1110. Even though nothing port-related needs to
be done in the CGU, there are some operations such as disabling the
watchdog clock which are unique to the SJA1110.

If @port is unused, then dsa_upstream_port(ds, port) returns @port,
which means we cannot assume the CPU port can be retrieved this way.

The sja1105 driver will gain support for the next-gen SJA1110 switch,
which is very similar except for the fact it has more than 5 ports.

So we need to replace the hardcoded SJA1105_NUM_PORTS in this driver
with ds->num_ports. This patch is as mechanical as possible (save for
the fact that ds->num_ports is not an integer constant expression).
