gpu: nvgpu: add error reporting support for L4T

Browse Source 
Add error reporting support for T194's L1SS safety
services for linux.

Used GA10B's LUT for GV11B. The error ids for T194 are
different compared to GA10B. This is handled by creating
a separate table mapping existing error ids to match GV11B.

Ids that are not used by GV11B are set to U32_MAX to indicate
the driver to not send them to the l1ss driver.
