The ECC sysfs stat creation function is called on GR init. GR can get
initialized multiple times but we only need to create the ECC stats
once. Therefore, add a check to avoid creating duplicate stat sysfs
nodes.

Add CILP support for gp10b by defining below function
pointers (with detailed explanation)
pre_process_sm_exception()
- for CILP enabled channels, get the mask of errors
- if we need to broadcast the stop_trigger, suspend all SMs
- otherwise suspend only current SM
- clear hww_global_esr values in h/w
- gr_gp10b_set_cilp_preempt_pending()
- get ctx_id
- using sideband method, program FECS to generate
interrupt on next ctxsw
- disable and preempt the channel/TSG
- set cilp_preempt_pending = true
- clear single step mode
- resume current SM
handle_fecs_error()
- we get ctxsw_intr1 upon next ctxsw
- clear this interrupt
- get handle of channel on which we first
triggered SM exception
- gr_gp10b_clear_cilp_preempt_pending()
- set cilp_preempt_pending = false
- send events to channel and debug session fd
