Sam Ravnborg 6943f3da3e sparc: move EXPORT_SYMBOL to the symbols definition
Move all applicable EXPORT_SYMBOL()s to the file where the respective
symbol is defined.

Removed all the includes that are no longer needed in sparc_ksyms_32.c

Comment all remaining EXPORT_SYMBOL()s in sparc_ksyms_32.c

Two symbols are shared with sparc64 thus the exports were removed from
the sparc_ksyms_64.c too, along with the include their ommission made
redundant.

Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

Additions by Julian Calaby:
* Moved EXPORT_SYMBOL()s for prom functions to their rightful places.
* Made some minor cleanups to the includes and comments of sparc_ksyms_32.c
* Made another subtraction from sparc_ksyms_64.c
* Updated and tidied commit message.
* Rebased patch over sparc-2.6.git HEAD.
* Ensured that all modified files have the correct includes.
