[PATCH] ARM: tegra: init fuse before setting reset handler

From: Alexandre Courbot <acourbot at nvidia.com>

CPU reset handler was set before fuse is initialized, but
tegra_cpu_reset_handler_enable() uses tegra_chip_id, which is set by
tegra_init_fuse(). This patch reorders the calls so the CPU reset
handler code does not read an uninitialized variable.

arm-soc, if you could apply this as a fix for 3.13, that'd be great.
Thanks.
