ARM: tegra: Initialize timer earlier
A subsequent patch will enable the use of the architected timer on ARMv8. Doing so implies that udelay() will be backed by this timer implementation, and hence the architected timer must be ready when udelay() is first called. The first time udelay() is used is while resetting the debug UART, which happens very early. Make sure that arch_timer_init() is called before that.
