Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:

CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down

All functions are weak or ifdef'ed so they can still be overriden by any
platform.

This Patch introduce the new i2c_core file, which holds
the I2C core functions, for the rework of the multibus/
multiadapter support.
Also adds changes in i2c.h for the new I2C multibus/multiadapter
support. This new support can be activated with the
CONFIG_SYS_I2C define.

Add hooks for tracing to generic board, including:

- allow early tracing to start early as possible in U-Boot
- reserve memory for trace buffer
- copy early trace buffer to main trace buffer after relocation
- setup full tracing support after relocation

Discard all .dynsym sections from linker scripts
Remove all __dynsym_start definitions from linker scripts
Remove all __dynsym_start references from the codebase

Note: this touches include/asm-generic/sections.h, which
is not ARM-specific, but actual uses of __dynsym_start
are only in ARM, so this patch can safely go through
the ARM repository.

This commit refactors common/board_f.c and common/board_r.c
in order to delete the dest_addr and dest_addr_sp from
gd_t struct.

As mentioned as follows in include/asm-generic/global_data.h,

  /* TODO: is this the same as relocaddr, or something else? */
  unsigned long dest_addr;        /* Post-relocation address of U-Boot */

dest_addr is the same as relocaddr.
Likewise, dest_addr_sp is the same as start_addr_sp.

It seemed dest_addr/dest_addr_sp was used only as a scratch variable
to calculate relocaddr/start_addr_sp, respectively.

With a little refactoring, we can delete dest_addr and dest_addr_sp.

The Freescale MPC8220 Power Architecture processors have long reached
EOL; Freescale does not even list these any more on their web site.

Remove the code to avoid wasting maitaining efforts on dead stuff.
