disable_interrupts() should return nonzero if interrupts were
_enabled_ before, not disabled.

The timer code depends on the timer interrupt to keep track of the
upper 32 bits of the cycle counter. This obviously doesn't work when
interrupts are disabled the whole time.

The ATSTK1000-specific flash driver intializes bi_flashstart,
bi_flashsize and bi_flashoffset, but other flash drivers, like the CFI
driver, don't.
Initialize these in board_init_r instead so that things will still be
set up correctly when we switch to the CFI driver.

Move the 64bit division from lib_avr32 to lib_generic. With this, all
boards can do_div/__div64_32 if needed, not only avr one. Code is put
to lib_generic, so no larger memory footprint if not used. No code
modifications. Thanks for proposal by Håvard Skinnemoen.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Implement MACB initialization for AVR32 and ATSTK1000, and turn
everything on, including the MACB driver.

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.

Relocate the u-boot image into SDRAM like everyone else does. This
means that we can handle much larger .data and .bss than we used to.

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.

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.
