93eeaf98c4 video: rockchip: mpp: Add task timing 
1. Add mpp device disable flag in procfs

Usage:

echo 1 > /proc/mpp_service/rkvenc-core0/disable
echo 1 > /proc/mpp_service/rkvdec-core0/disable

2. Add task timing record for timeout issue debug.

Usage echo timing threshold to hardware device:

echo 1 > /proc/mpp_service/timing_en
echo 10000 > /proc/mpp_service/rkvenc-core0/timing_check
echo 10000 > /proc/mpp_service/rkvenc-core1/timing_check
