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.

The Tegra clocksource implementation uses the clocksource_mmio helper

drivers/clocksource/built-in.o: In function `tegra20_init_timer':
:(.init.text+0xac): undefined reference to `clocksource_mmio_init'

The same problem exists for Digicolor:

:(.init.text+0xfa): undefined reference to `clocksource_mmio_init'

I've inspected the Kconfig file to look for other cases that I have not
