[PATCH] soc: tegra: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

return type of wait_for_completion_timeout is unsigned long not int. An
appropriately named unsigned long is added and the assignment fixed up.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

This was only compile tested for tegra_defconfig 
(implies CONFIG_ARCH_TEGRA_2x_SOC=y)

Patch is against 4.0-rc2 linux-next (localversion-next is -next-20150306)
