AVR32: Use initdram() instead of board_init_memories()
Conform to the "standard" interface and use initdram() instead of
board_init_memories() on AVR32. This enables us to get rid of the
sdram_size member of the global_data struct as well.
Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.
Add -fPIC -mno-init-got to the avr32-specific CFLAGS to make u-boot
position independent. This will make relocation a lot easier.
-mno-init-got means that gcc shouldn't emit code to load the GOT
address into r6 in every function prologue. We do it once and for
all in the early startup assembly code, so enabling this option
makes u-boot a bit faster and smaller.
The assembly parts have always been position-independent, so no code
changes should be necessary.
AVR32: Split start_u_boot into board_init_f and board_init_r
Split the avr32 initialization code into a function to run before
relocation, board_init_f and a function to run after relocation,
board_init_r. For now, board_init_f simply calls board_init_r
at the end.

ppc4xx: Fix i2c divisor calcularion for PPC4xx
This patch fixes changes the i2c_init(...) function to use the function
get_OPB_freq() rather than calculating the OPB speed by
sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is
specific per processor. The prior method was not and so was calculating
the wrong speed for some PPC4xx processors.

Write a "pixis_reset" command that utilizes the FPGA
