f3f14cdff5 gpu: nvgpu: Fold T19x code back to main code paths
Lots of code paths were split to T19x specific code paths and structs
due to split repository. Now that repositories are merged, fold all of
them back to main code paths and structs and remove the T19x specific
Kconfig flag.

3ccf5c85fb gpu: nvgpu: add g->sw_ready flag
Fix a race condition where we'd still be booting up the gpu and/or
initializing the driver but elsewhere assume that all is done already.

Some userspace APIs to make sure that we're ready by testing
g->gr.sw_ready, but this flag is set in the middle of bootup; there are
other things after gr initialization. Add a new flag that is enabled
after bootup is fully complete at the end of finalize_poweron, and
change the checks in user API paths to test the new flag only.

These checks are only in the ioctl paths for ctrl, dbg and tsg, and in
the ctrl device's opening path.

The gr.sw_ready flag is still left there to signify whether just gr has
had its bookkeeping initialized.

536ec21b56 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.

So until VGPU code is properly abstracted and made os-independent,
