gpu: nvgpu: add ioctl to configure implicit ERRBAR

Browse Source 
Add ioctl support to configure implicit ERRBAR by setting/unsetting
NV_PGRAPH_PRI_GPCS_TPCS_SM_SCH_MACRO_SCHED register.

Add gpu characteritics flag: NVGPU_SCHED_EXIT_WAIT_FOR_ERRBAR_SUPPORTED
to allow userspace driver to determine if implicit ERRBAR ioctl is
supported.
