gpu: nvgpu: debugfs node to enable/disable ltc_illegal_compstat intr

Added debugfs node under ltc directory with name:
intr_illegal_compstat_enable

Enabling/disabling of ltc_illegal_compstat intr is
possible through debugfs node.

Since ltc state is lost with rail gate, this setting is
cached and will be populated during ltc initialization.
