Configuration of this crucial variable should still be somewhat

The MPC8349EMDS configuration was the basis for the sbc8349, so it also
contains its SDRAM option.

Since
* the SDRAM has to be soldered onto the board,
* the sbc8349 never used the support, and
* the support never worked (see previous patch fixing it),

we can assume that the support on the sbc8349 is an artifact created by
copying the MPC8349EMDS config wholesome.

Hence, instead of creating a separate sbc8349 config that supports
SDRAM, we can remove the SDRAM option for this board.

Should it be needed in the future, it can be copied from the new
MPC8349EMDS_SDRAM board.

Re-format all BR,OR #define lines into single lines. This makes them

We want to normalize all BR/OR config lines as much as possible.

The TQM834x board uses CONFIG_SYS_OR_TIMING_FLASH in a OR definition,
which we want to remove. But CONFIG_SYS_OR_TIMING_FLASH is also used
outside of the config file.

Replace these usages with the definition of the variable, so we can
remove the variable in the next patch.

MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the
system clock. To migrate the architecture, we can replace
CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ.

To do this
* replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
* set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
  MPC83xx config files
Signed-off-by: NMario Six <mario.six@gdsys.cc>

CONFIG_SYS_CLK_FREQ is the standard way to set the system clock
frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose.
Hence, the obvious way is to replace CONFIG_83XX_CLKIN with
CONFIG_SYS_CLK_FREQ.

A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing
CONFIG_SYS_NS16550_CLK. This makes it harder to replace
CONFIG_83XX_CLKIN.

But the value of the multiplicator can be read from the SPMR register.

Hence, replace the static calculations with a call to a new get_bus_freq
function, as other architectures do.

The ve8313 has the option of either configuring the eLBC (enhanced local system bus) such that

* NOR flash is the first memory bank, and NAND flash is the second memory bank, or
* NAND flash is the first memory bank, and NOR flash is the second memory bank,

by using CONFIG_SYS_NOR_{BR,OR}_PRELIM and
CONFIG_SYS_NAND_{BR,OR}_PRELIM for defining
CONFIG_SYS_{BR,OR}{0,1}_PRELIM.

After Kconfig migration, replacing some lines in the defconfig will have
the same effect.

Hence, we will not create distinct ve8313_{NOR,NAND} configs for such a
small change.

Instead, fix the current default (NOR first, NAND second), and unroll

The LSDMR_* macros are used to configure the system bus on MPC83xx.

A few of the possible LSDMR_* macros were never defined in the
