Rather than using 8bit transfers for everything, use 8/16/32 bit transfers

The performance difference from doing an 8 bit DMA memcpy vs an optimized
core memcpy can be pretty big when you add in the overhead of setting up the
MDMA registers, cache flushes, etc...  So only use dma_memcpy() when we
actually require it.

We have to make sure the DMA channel is actually disabled in hardware before
attempting to reprogram it.  Otherwise the new settings are ignored and we
end up with random hangs/failures.

Take the cache flush functions from the kernel as they use hardware loops in

Calculating the clocks requires a bit of calls to gcc math functions, so
cache the values after the first run since they'll most likely never
change once U-Boot is up and running.

This patch adds support for searching through available PHY-addresses in
the macb-driver. This is needed for the ATEVK1100 evaluation board,
where the PHY-address will be initialized to either 1 or 7.

This patch adds a config option, CONFIG_MACB_SEARCH_PHY, which when
enabled tells the driver to search for the PHY address.

This patch removes volatile from:
volatile IP_t *ip = (IP_t *)xip;

Due to a bug, avr32-gcc will assume that ip is aligned on a word boundary when
using volatile, which causes an exception since xip isn't aligned on a word
boundary.
