Add support to store error state of single SM before
preprocessing SM exception
Error state is stored as :
struct nvgpu_dbg_gpu_sm_error_state_record {
u32 hww_global_esr;
u32 hww_warp_esr;
u64 hww_warp_esr_pc;
u32 hww_global_esr_report_mask;
u32 hww_warp_esr_report_mask;
}
Note that we can safely append new fields to above
structure in the future if required
Also, add IOCTL NVGPU_DBG_GPU_IOCTL_READ_SINGLE_SM_ERROR_STATE
to support reading SM's error state by user space

The current CUDA drivers have been using the regops to
directly accessing the GPU registers from user space through
the dbg node. This is a security hole and needs to be avoided.
The patch alternatively implements the similar functionality
in the kernel and provide an ioctl for it.

The default zbc entries were never populated in zbc HW table
because the conditional flag "gr->sw_ready" was always set thus
avoided the zbc default loading function call. Now zbc default
loading would happen only during boot time in sw structure.Hw
zbc regs would be loaded from that structure every time a
railgate exit happens.
