clocksource: fixup ux500 build problems
Based on a patch from Arnd Bergmann this fixes up the build problem of assigning a non-existing global when the ux500 PRCMU timer is not linked in by passing its base address to the init function. We also add a missing <linux/errno.h> inclusion and staticize the dummy function. Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
