Some lines of the U-boot DM9000x driver are longer than 80 characters, or
need some other minor cleanup.

The DM9000A network controller does not work with the U-boot DM9000x driver.
Analysis showed that many incoming packets are lost.
The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to
check for a valid rx packet be done on the interrupt status register, not
directly by performing the dummy read and the rx status check as is currently
the case in the u-boot driver.
When the recommended poll is done as suggested the driver starts working
correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there
can be more than 1 package in the fifo at the same time.
The driver must perform the rx-status check in a loop and read and handle all
packages until there is no more left _after_ the interrupt RX flag is set.
This change has been tested with DM9000A, DM9000E, DM9000EP.

According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the
reset procedure must be done twice to properly reset the DM9000 by means of software.
This errata is not needed anymore for the DM9000A, but it does not bother it.
This change has been tested with DM9000A, DM9000E, DM9000EP.

The eth_send routine of the U-boot DM9000x driver does not match the
DM9000 or DM9000A application notes/programming guides.
This change improves the stability of the DM9000A network controller.

It seems that the debugging code of the DM9000x driver in U-boot has not been
compiled for a long time, because it cannot compile...
Also rearranged some loglines to get more useful info while debugging.

The U-boot DM9000x driver contains a compile time bus-width definition for
the databus connected to the network controller.
This compile check makes the code unclear, inflexible and is unneccessary.
It can be asked to the network controller what its bus-width is by reading bits
6 and 7 of the interrupt status register.
The linux kernel already uses a runtime mechanism to determine this bus-width,
so the implementation below looks somewhat like that implementation.
This change has been tested with DM9000A, DM9000E, DM9000EP.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

This way we become able to utilize the full post_log_word for POST
activities (overwise, POST ECC, which has 0x8000 ID, could be
erroneously treated as started in post_output_backlog() even if there
was actually no POST ECC run (because of OCM POST failure, for
example).

Switch the OCM testid with the codec one. The reason is that current
implementation requires the POST_ROM testid to fit into lower 16
bits, and the codec test will never run with POST_ROM hopefully.

When SATA is selected (via jumper J6) we need to disable the first PCIe
node in the device tree, so that Linux doesn't initialize it. Otherwise
the Linux SATA driver will fail to detect the devices.
The same goes the other way around too. So if PCIe is selected we need
to disable the SATA node in the device tree.
This is because PCIe port 0 and SATA on 460EX share the same pins
(multiplexed) and we have to configure in U-Boot which peripheral is
enabled.
