tlkd: remove system off/reset handlers
TLK does not participate in the system off/reset process and so has no use for the SYSTEM_OFF/RESET notifications. This patch removes the system off/reset handlers as a result. Change-Id: Icf1430b1400cea88000e6d54426eb604a43cbe6c Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>
