Minor cleanup to clock-related defines for DaVinci DM6446 boards:

 - CONFIG_SYS_CLK_FREQ is unused; remove it.

 - CONFIG_SYS_NS16550_CLK must be the same as CONFIG_SYS_HZ_CLOCK

On DM6446 both of those peripheral clocks actually come from the
same source, the primary oscillator.  Having them use the same
symbol avoids bugs in the clone'n'modify development cycle.

The patch fixes the bug of partial initialization of global network
parameters.

Upon u-boot's start up the first ping command causes a failure of the
consequent TFTP command. It happens in the recently added mechanism of
the NetLoop initialization where initialization of global network
parameters is separated in the NetInitLoop routine which is called per
env_id change. Thus, ping request will initialize the network parameters
necessary for ping operation only, afterwards the env_changed_id will be
set to the env_id that will prevent all following initialization requests
from other protocols.
The problem is that the initialized by ping subset of network parameters
is not sufficient for other protocols and particularly for TFTP which
requires the NetServerIp also.

Update the DaVinci DM6446 boards to use the new convention
for CONFIG_SYS_NS16550_REG_SIZE ... the size hasn't changed
from the original 4 bytes, but these chips are little-endian.

(Resolves a regression added recently by the include/ns16550.h
patch to "Unify structure declaration for registers".  The code
previously worked just fine because the registers were accessed
as host-endian words, not as bytes.)

Currently the NOR & NAND support in Linux only works for the "standard"
Sequoia, the version booting for NOR flash. The NAND-booting version
has the chip-selects swapped. Here the chip-select mappings:

"Standard" NOR-booting version:
CS0	NOR
CS3	NAND

NAND-booting version:
CS0	NAND
CS3	NOR

With this path the dtb gets fixed-up, so that the correct chip-select
numbers are patched in the dtb enabling correct NOR & NAND support
in Linux on the NAND-booting Sequoia version.

DESCRIPTION:
The column address width settings for banks 2 and 3 are misconnected in
the SDRAM controller.  Accesses to bank 2 will result in an error if the
Column Address Width for bank 3 (EB3CAW ) is not set to be the same as
that of bank 2.

WORKAROUND:
If using bank 2, make sure that banks 2 and 3 have the same column address
width settings in the EBIU_SDBCTL register.  This must be the case
regardless of whether or not bank 3 is enabled.

DESCRIPTION:
If the DF bit is set prior to a hardware reset, the PLL will continue to
divide CLKIN by 2 after the hardware reset, but the DF bit itself will be
cleared in the PLL_CTL register.

WORKAROUND:
Reprogram the PLL with DF cleared if the desire is to not divide CLKIN by
2 after reset.

Blackfin SPI driver was not driving the SPI chip-select high before
putting the chip-select signals into tri-state mode.  This is probably
something that slipped by unnoticed in most designs.  If the signals are
put directly into a tri-state mode, then the board is relying on the
pull-up resistors to pull up the chip-select before the next transaction.
Most of the time this is fine, except when you have two transactions that
follow each other very closely, such as the flash erase and read status
register commands.  In this case I was seeing a 500ns separation between
the transactions.  In my setup, with a 10kOhm pull-up, it would meet
timing spec about half the time and resulted in intermittent errors.  (A
stronger pull up would fix this, but our design is targeted for low power
consumption and a 3.3kOhm @ 3.3v is 3.3mW of needless power consumption.)
I modified the spi_cs_deactivate() function in bfin_spi.c to drive the
chip-selects high before putting them into tri-state.  For me, this
resulted in a rise time of 5ns instead of the previous rise time of about
1us, and fully satisfied the timing spec of the chip.
