PATCH v2 1/1 ARM: at91: Export at91_st_base

After commit 5e9cf5e18d4b "ARM: at91: make ST (System Timer) soc independent" building at91rm9200_wdt as a module fails with following message
ERROR: "at91_st_base" [drivers/watchdog/at91rm9200_wdt.ko] undefined! make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

Export symbol to allow wdt driver to be built as a module again.

v2: Changed symbol export to GPL as per request from Jean-Christophe PLAGNIOL-VILLARD.
