9fbd6d0ba0 b53: fix memory out of bounds access on 64 bit targets
On device reset the sizes for the vlan and port tables were wrongly
calculated based on the pointer size instead of the struct size. This
causes buffer overruns on 64 bit targets, resulting in panics.

Fix this by dereferencing the pointers.

d24d5412ff b53: widen stp state mask to 3 bits (instead of 2)
At least on my b53 chip, the mask is 3 bits wide, and because
of this some STP states are not set properly and discarded when read.

Maybe for some other chips it makes sense to have just 2 bits width,
but I don't have other versions around to test/validate.

If that's the case then maybe we could add another STP state mask.

e93c68eedd b53: Allow using all ports on BCM53012
This chipset has at least 8 usable ports, e.g. Netgear R8000 has ports
5, 7 and 8 connected to Ethernet interfaces:
vlan1ports=0 1 2 3 5 7 8*
vlan2ports=4 8u
Port 6 seems to be always disabled.

06ac2f5c74 b53: improve overriding CPU port state on BCM5301X
On BCM5301X there are two different cases to handle: CPU port 8 vs. any
other one. Support for CPU port 8 was already partially implemented but
it lacked setting some extra bit for 2G speed. It also will need to be
extended to implement "SMP dual core 3 GMAC setup". That's the reason
for handling it in separated code block.
This patch also adds overriding CPU port state for port other than 8. It
requires using recently defined GMII_PORT registers.
It was tested for regressions on BCM53011 revs 2 & 3. It was also
confirmed to fix switch on some internal Broadcom board.

d75cd5be37 b53: fix mmap register read/writes > 32 bit
For bcm63xx integrated switches, broadcom changed the data endianess
to match the system endianess. But this only applies to within one word,
which causes 48/64 bit values to be still split into their "litte endian"
groups.

E.g. 48 bit values (with 5 being the most significant byte) aligned

0x00 ..01  or   0123
0x04 2345       45..

will become

0x00 ..10 resp. 3210
0x04 5432       54..

Likewise for 64 bit values.

b53 uses GPIO 7:
