[U-Boot] [PATCH] Adds general Freescale CodeWarrior debug support

[Roy Zang]

This patch adds general CodeWarrior debug support.
Patch is tested on 85xx/QorIQ platforms in u-boot.
CONFIG_DEBUG_CODEWARRIOR should be defined if the u-boot needs to be
debugged by CodeWarrior.
To use the CodeWarrior debug funciton, the make command can be just as
make CONFIG_DEBUG_CODEWARRIOR=1
