bb2c8b1fc4 nvsciipc: increase inter-process channel count 
default DriveOS inter-process endpoint count is about 1300 for now.
DriveAV requirement needs 8192 inter-process channels
(=16384 endpoints) except for DriveOS system usage.
Hence increased the number of inter-process endpoints by 2048
more in considering margin.
