clocksource: Build Tegra timer on 32-bit ARM only
Instead of directly using the ARCH_TEGRA Kconfig symbol to enable this
driver, add a new, non-user-visible Kconfig symbol (TEGRA_TIMER) which
can be selected by the various SoCs.
This is useful to disable building the driver on Tegra132 (64-bit ARM)
where it doesn't currently compile but also isn't needed (yet).
