Fix two buglets in the dm644x support:  don't set two must-be-zero
bits in the UART management register; and only include the I2C hooks
if the I2C driver is being included.

Split out DaVinci DM6446-specific bits from more generic bits:

 - Add a CONFIG_SOC_DM644X.  All current boards use DM6446 chips;
   DM6443 and DM6441 chips differ in available peripherals.

 - Move most DM644X-specific bits from psc.c to a new dm644x.c file,
   which is conditionally built.  It provides device-specific setup.

Plus minor coding style and comment updates with respect to the PSC.

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.

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.
