Subject: [PATCH] [media] pulse8-cec: Eliminate use of time_t and time_to_tm

Eliminate the use of time_t type and time_to_tm function as they are
deprecated due to the 32-Bit interface which will overflow in year 2038.
Therefore use the 64-Bit type interface which is time64_t and time64_to_tm
instead to avoid y2038 overflow problem.

0-day tested without any issues!
