DM9000 fix status check fail 0x6d error for trizeps board
According to the Application Notes of the DM9000, only the 2 bits 0:1 of
the status byte need to be checked to identify a valid packet in the fifo
But, The several different Application Notes do not all speak the same
language on these bits. They do not disagree, but only 1 Application Note
noted explicitly that only these 2 bits need to be checked.
Even the datasheets do not mention anything about these 2 bits.
Because the old code, and the kernel check the whole byte, I left this piece
untouched.
However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so
it should work.
Notice, that the 2nd iteration through this receive loop (when a 2nd packet is
in the fifo) is much shorter now, compared to the older U-boot driver code,
so that we can maybe run into a hardware condition now that was never seen
before, or maybe was seen very unfrequently.
Additionaly added a cleanup of a stack variable.

Get rid of annoying/superfluous bad-checksum warning message
U-boot can complain a lot about 'checksum bad' when it is attached to the network.
It is annoying for ordinary users who start to doubt the network connection
in general when they see messages like this.
This is caused by the routine NetCksumOk() which cannot handle IP-headers longer
than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them
now before checking the checksum.

DM9000: Make driver work properly for DM9000A
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.

DM9000: Add data bus-width auto detection.
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.

ppc4xx: Canyonlands: Disable PCIe0/SATA in dev-tree depending on selection
When SATA is selected (via jumper J6) we need to disable the first PCIe

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.
