uml: style fixes pass 1

Formatting changes in the files which have been changed in the
tt-removal patchset so far.  These include:
	copyright updates
	header file trimming
	style fixes
	adding severity to printks
	indenting Kconfig help according to the predominant kernel style

These changes should be entirely non-functional.
