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.
