The Freescale P1022DS can use either a 12.288MHz or a 11.2896MHz reference
clock for the audio codec, but by default both are disabled. Add a 'audclk'
hwconfig option that allows the user to choose which clock he wants.
The 12.288MHz clock allows the codec to use sampling rates of 16, 24, 32, 48,
64, and 96KHz. The 11.2896 clock allows 14700, 22050, 29400, 44100, 58800, and
88200Hz.
Also configure a pin muxing to select some SSI signals, which will disable
I2C1.

On the Freescale P1022, the DIU and the LBC share address pins, which means
that when the DIU is active (e.g. the console is on the DVI display), NOR flash
cannot be accessed. So we use the weak accessor function feature of the CFI
flash code to temporarily switch the pin mux from DIU to LBC whenever we want
to read or write flash. This has a significant performance penalty, but it's
the only way to make it work.
This change allows the 'saveenv' command to work when the video display is
enabled. Erasing flash and writing to flash (with the 'cp' command) works,
but reading from flash (with the 'md' and 'cp' commands) does not. Also, while
flash is being written, the video display will be blank.

Add support for the DIU controller. If CONFIG_VIDEO is defined, then
the console will appear on a DVI monitor instead of the serial port.

Previously we used an alias the pci node to determine which node to
fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to
find the node to update.
Additionally, we replace the code in each board with a single macro call
that makes assumes uniform naming and reduces duplication in this area.

The code to map SERDES configs to slot names is board specific and not
chip specific. Thus it should live in board/freescale/p1022ds/ and not
in arch/powerpc/cpu/.
