gpu: nvgpu: remove dependency on linux header for regops_gk20a*

This patch removes the dependency on the header file "uapi/linux/nvgpu.h"
for regops_gk20a.c. The original structure and definitions in the
uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The
following changes are made in this patch.

1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside
regops_gk20a.h.
2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside
regops_gk20a.h naming it struct nvgpu_dbg_reg_op.
3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from
linux versions to common and vice versa.
4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to
struct nvgpu_dbg_reg_op and vice versa.
5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from
userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which
is copied into the struct nvgpu_dbg_reg_op using the APIs above and
after executing the regops handler passes the data back into userspace
by copying back data from struct nvgpu_dbg_reg_op to struct
nvgpu_dbg_gpu_reg_opi.
