We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to
arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16.
Introduce select statements for other architectures based on current
usage.  For MIPS, we take the existing arch-specific symbol and migrate
to the generic symbol.  This lets us remove a little bit of otherwise
unused code.

- In most of the codebase, we reference CONFIG_SYS_LOAD_ADDR and not

All platforms define CONFIG_SYS_LOAD_ADDR, but only some define
CONFIG_LOADADDR.  Very very rarely are these not the same address, and
qemu-ppce500 is one such case.  However, based on reading the history of
the code, this mismatched value was simply a copy-paste from other
PowerPC platforms where it is this unused currently.  Switch the code to
use CONFIG_SYS_LOAD_ADDR and update the documentation.

As this symbol can either be a fixed value or the function
get_board_ddr_clk, migration is tricky.  Introduce a choice of DYNAMIC
or STATIC_DDR_CLK_FREQ.  If DYNAMIC, we continue to use the board
defined get_board_ddr_clk function.  If STATIC, set CONFIG_DDR_CLK_FREQ
to that value and now include/clock_legacy.h contains the function
prototype or defines get_board_ddr_clk() to that static value.  Update
callers to test for DYNAMIC or STATIC.

- Begin merging some Kconfig migration, and CONFIG namespace cleanup
  series in.  This gives us:
  - A number of I2C symbols migrated over
  - DWC2, i8042, altera_spi and a few other areas updated to use CFG not
    CONFIG for the concept of "configuration space" defines.
  - Rename CONFIG_EXTRA_ENV_BOARD_SETTINGS to EXTRA_ENV_BOARD_SETTINGS
  - Some dead code removal.
  - Rename a number of CONFIG symbols that were only referenced within
    the config header to not use CONFIG as a prefix.

While the Kconfig language seems to accept either form of whitespace, we
use a space throughout the project, except in these spots.
