clocksource: Select CLKSRC_MMIO where needed
The Tegra clocksource implementation uses the clocksource_mmio helper functions, but currently can be configured without them, which fails: drivers/clocksource/built-in.o: In function `tegra20_init_timer': :(.init.text+0xac): undefined reference to `clocksource_mmio_init' :(.init.text+0x140): undefined reference to `clocksource_mmio_readl_up' The same problem exists for Digicolor: drivers/clocksource/built-in.o: In function `digicolor_timer_init': :(.init.text+0xfa): undefined reference to `clocksource_mmio_init' :(.init.text+0x14c): undefined reference to `clocksource_mmio_readl_down' I've inspected the Kconfig file to look for other cases that I have not yet run into, and added an explicit 'select' to each one to ensure we can successfully link the drivers.
