Add an implementation of the timer functions for tegra, so that timing

I'm a bit confused about this:
include/configs/tegra-common.h:32:#define CONFIG_SYS_TIMER_COUNTER
NV_PA_TMRUS_BASE
lib/time.c:
#ifdef CONFIG_SYS_TIMER_COUNTER
unsigned long notrace timer_read_counter(void)
{
#ifdef CONFIG_SYS_TIMER_COUNTS_DOWN
return ~readl(CONFIG_SYS_TIMER_COUNTER);
#else
return readl(CONFIG_SYS_TIMER_COUNTER);
#endif
}
Doesn't that provide the same set of features, without requiring
Tegra-specific code?
