Subject: [PATCH] clocksource: atmel_tcb: fix kconfig dependency

From: Arnd Bergmann <arnd@...db.de>

Build-testing this driver on arm without CONFIG_OF produces a warning:

drivers/clocksource/timer-atmel-tcb.c:368:34: error: 'atmel_tcb_of_match' defined but not used [-Werror=unused-const-variable=]
  368 | static const struct of_device_id atmel_tcb_of_match[] = {
      |                                  ^~~~~~~~~~~~~~~~~~

Change the dependency to allow build-testing on all architectures but
instead require CONFIG_OF to be present.

I saw this for the first time today in a randconfig build, but I think this
has been around for a long time without ever showing up in random
configs.
