Cleanup: Timing adapter definitions

The NPU timing adapter base addresses had been defined in mutiple
places, making it difficult to determine which one is actually being
used. This patch cleans up unused definitions from memory-map header
files for different targets and the CMake template files.

The expectation is for component base addresses to be set by platform
specific CMake files that include/wrap the component directories.
