Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

Add support for this command, moving away from the previous approach of
hard-coding the initial data in the driver, now that the kernel-space data
has to be set up by the higher-level vboot code.

We want to support nvdata in TPM2 as well. To avoid code duplicating the
associated code, move it into a common file.

Drop the special-case logic for the kernel space. This can be handled by
the higher-level code now, i.e. in vboot itself.
