Move DaVinci PSC support from board/* to cpu/* where it belongs.
The PSC module manages clocks and resets for all DaVinci-family
SoCs, and isn't at all board-specific.

Chips without the EMAC controller won't need the utilities
it uses to read an Ethernet address from EEPROM; so don't
include them needlessly.
Use is_valid_ether() to validate the address from EEPROM.
All-zero addresses aren't the only invalid addresses.
A fully erased EEPROM returns all-ones, also invalid...
Switch those Ethernet utilities to use "%pM" for printing
MAC addresses; and not say ROM when they mean EEPROM.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

Taken all the duplicated code for enabling common modules and apply
software workarounds from the board specific code into common
functions. Also added comments explaining the workarounds
(from TI errata documents) and replaced some numerical bit numbers
with more meaningful defines.

Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA
Changes:
- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
DV_EVM. Can't check if it works on SONATA, don't have a board any more,
but it at least compiles.
Here is an excerpt from session log on SCHMOOGIE...
