This patch fixes a problem spotted by Mikhail Zolotaryov on Sequoia with
the DDR2 configuration to only use one CS (rank). As this code is most
likely copied from the original Sequoia version, this error was copied
as well.
This patch also removes some dead code.

Sequoia board schematics (DES0211_11_SCH_11.pdf, page 5, unit U1D)
specifies that BankSel#1 is not connected, while bootloader memory
configuration is (board/amcc/sequoia/sdram.c):
mtsdram(DDR0_10, 0x00000300);
i.e. both Chip Selects used - not correct.
If we change to correct value here:
mtsdram(DDR0_10, 0x00000100);
memory is accessible OK also.

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.

add CONFIG_BOOTCOUNT_LIMIT feature for 8360 CPU.
The bootcounter uses 8 bytes from the muram,
because no other memory was found on this
CPU for the bootcount feature. So we must
correct the muram size in DTS before booting
Linux.
This feature is actual only implemented for
MPC8360, because not all 83xx CPU have qe,
and therefore no muram, which this feature
uses.
