tee: add ARM_SMCCC dependency
For the moment, the tee subsystem only makes sense in combination with the op-tee driver that depends on ARM_SMCCC, so let's hide the subsystem from users that can't select that. Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
