Implement nvgpu plumbing to allow reporting ECC errors(corrected and uncorrected) to a L1SS service(if one exists). This patch includes the following 1) Added code that submits ECC error reports via the Interrupt context directly to a L1SS service in linux OS. 2) Added support for enabling/disabling the error reports via L1SS's registration/deregistration API. Nvgpu simply invokes an empty function until the registration is successful. 3) Added Spinlock to correctly handle concurrency for accessing the correct Ops for submitting requests. 4) Adds error reporting for a subset of interrupts that can be verified via external ECC injection logic. A subsequent patch will add the API for rest of the interrupts. 5) In case of critical(uncorrected errors), change nvgpu's state to quiesce state.
