[PATCH v2] drm/msm: Use 64-bit timekeeping

[Tina Ruchandani <ruchandani.tina@gmail.com>]

'struct timespec' uses a 32-bit seconds which will overflow in year
2038 and beyond. This patch replaces timespec with timespec64. The
code is correct as is - the patch is merely part of a larger attempt
to remove all 32-bit timekeeping variables (timespec, timeval, time_t)
from the kernel.
