Now that all prerequisites are in place, drop the two-stage driver
instances initialization in favor of the following simple init sequence:
1. Probe PCI device: we only test ECC capabilities here and if none exit
early.
2. If the hw supports ECC and it is/can be enabled, we init the per-node
instance.
Remove "amd64_" prefix from static functions touched, while at it.
There actually should be no visible functional change resulting from
this patch.

Rework the code to check the hardware ECC capabilities at PCI probing
time. We do all further initialization only if we actually can/have ECC
enabled.
While at it:
0. Fix function naming.
1. Simplify/clarify debug output.
2. Remove amd64_ prefix from the static functions
3. Reorganize code.

This is in preparation for the init path reorganization where we want
only to
1) test whether a particular node supports ECC
2) can it be enabled
and only then do the necessary allocation/initialization. For that,
we need to decouple the ECC settings of the node from the instance's
descriptor.
The should be no functional change introduced by this patch.

PCI ECS is being enabled by default since 2.6.26 on AMD so this code is
just superfluous now, remove it.

Remove static allocation in favor of dynamically allocating space for as
many driver instances as northbridges present on the system.

Move the remaining per-family init code into the proper place and

Run a per-family init function which does all the settings based on
the family this driver instance is running on. Move the scrubrate
calculation in it and simplify code.

Move 'main' code vs. subroutines around so that they are not so
intermixed, for better readability/understanding (relative to Perl).
It was messy to follow the primary flow of code execution with the
code being mixed. Now the code begins with data initialization,
followed by all subroutines, then ends with the main code execution.
This is almost totally source code movement, with a few changes as
needed for forward declarations.
