The MPC83xx DM timer driver disables arch.pciexp*_clk, and uses
clk_get_rate instead. But the legacy MPC83xx PCIe driver still uses
arch.pciexp*_clk for the clock.
Hence, read the PCIe clock from the registers in the legacy MPC83xx PCIe
driver.

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: Mario 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 MPC8349EMDS config file contains config options to enable SDRAM

The LSDMR_* macros are used to configure the system bus on MPC83xx.
A few of the possible LSDMR_* macros were never defined in the
respective include files. This renders the SDRAM support on the
MPC8349EMDS unusable, because it uses these undefined macros.
To make the SDRAM option work, introduce these macros into the proper
config file.

CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig
parameters; only for the ARC architecture. This patch turns these two
parameters into Kconfig items everywhere else they are found.
All of the include/configs/* and defconfig changes in this patch are
for arm machines only. The Kconfig changes for arc, nds32, riscv,
and xtensa have been included since these symbols are found in code
under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined
include/configs/* or defconfigs for these architectures exist which
include these symbols.
These results have been confirmed with tools/moveconfig.py.

According to De Morgan's Law[1]:
!(A && B) = !A || !B
!(A || B) = !A && !B
There are 5 places in the code where we find:
#if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
and 4 places in the code where we find:
#if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF))
In words, the construct:
!defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
"is the [DI]CACHE on?"
and the construct:
defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
"is the [DI]CACHE off?"
Therefore
!(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
means:
"the opposite of 'are they both off?'"
in other words:
"are either or both on?"
and:
(!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)
means:
"are either or both on?"
As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for
consistency.
