Moved the mdio regs out of the tsec structure,and
provided different offsets for tsec base and mdio
base so that provision for etsec2.0 can be provided.
This patch helps in providing the support for etsec2.0
In etsec2.0, the MDIO register space and the etsec reg
space are different.
Also, moved the TSEC_BASE_ADDR and MDIO_BASE_ADDR definitons into
platform specific files.

Previously, waiting for auto-negotiation would only occur if a valid
link had been detected. Problems arose when attempting to use a
tsec immediately after bootup but before link was achieved, eg:
=> dhcp
Auto-neg error, defaulting to 10BT/HD
eTSEC1: No link.
Auto-neg error, defaulting to 10BT/HD
eTSEC2: No link.
=>
With this patch applied the same operation as above resulted in:
=> dhcp
Waiting for PHY auto negotiation to complete. done
Enet starting in 1000BT/FD
Speed: 1000, full duplex

Commit af1c2b84 added a generic phy support, with an ID of zero
and a 32 bit mask; meaning that it will match on any PHY ID.
The problem is that there is a test that checked if a matching
PHY was found, and if not, it printed the non-matching ID.
But since there will always be a match (on the generic PHY,
worst case), this test will never trip.
In the case of a misconfigured PHY address, or of a PHY that
isn't explicitly supported outside of the generic support,
you will never see the ID of 0xffffffff, or the ID of the
real (but unsupported) chip. It will silently fall through
onto the generic support.
This change makes that test useful again, and ensures that
the selection of generic PHY support doesn't happen without
some sort of notice. It also makes it explicitly clear that
the generic PHY must be last in the PHY table.

SOFT_RESET must be asserted for at least 3 TX clocks. Usually, that's about 30
clock cycles, so it's been mostly working. But we had no guarantee, and at
slower bitrates, it's just over a microsecond (over 1000 clock cycles). This
enforces a 2 microsecond gap between assertion and deassertion.

This patch tries to ensure that phy interrupt pin
won't be asserted after booting. We experienced
following issues with current 88E1121R phy init:
Marvell 88E1121R phy can be hardware-configured
to share MDC/MDIO and interrupt pins for both ports
P0 and P1 (e.g. as configured on socrates board).
Port 0 interrupt pin will be shared by both ports
in such configuration. After booting Linux and
configuring eth0 interface, port 0 phy interrupts
are enabled. After rebooting without proper eth0
interface shutdown port 0 phy interrupts remain
enabled so any change on port 0 (link status, etc.)
cause assertion of the interrupt. Now booting Linux
and configuring eth1 interface will cause permanent
phy interrupt storm as the registered phy 1 interrupt
handler doesn't acknowledge phy 0 interrupts. This
of course should be fixed in Linux driver too.

The tsec driver contains a hard-coded array of configuration information
for the tsec ethernet controllers. We create a default function that works
for most tsecs, and allow that to be overridden by board code. It creates
an array of tsec_info structures, which are then parsed by the corresponding
driver instance to determine configuration. Also, add regs, miiregs, and
devname fields to the tsec_info structure, so that we don't need the kludgy
"index" parameter.

The Vitesse VSC8601 RGMII PHY has internal delay for both Rx
and Tx clock lines. They are configured using 2 bits in extended
register 0x17.
Therefore CFG_VSC8601_SKEW_TX and CFG_VSC8601_SKEW_RX have
been introduced with valid values 0-3 giving 0.0, 1.4,1.7 and 2.0ns delay.
