NVGPU_DBG_GPU_IOCTL_REG_OPS currently doesn't return if the ctx was
resident in engine or not.
Regops are broken down into batches of 128 and each batch is executed
together. Since there only 32 bits were available in IOCTL args, returning
is ctx was resident isn't possible for all batches.
Hence return if the ctx was resident for the first batch.

In nvgpu_ioctl_channel_reg_ops(), we right now first check if context is
allocated or not and if context is not allocated we fail the regops operation
But it is possible that the regops operation only includes global regops which
does not need global context allocated
So move this global context check from nvgpu_ioctl_channel_reg_ops() to
exec_regops_gk20a() and only if we have context ops included in the regops

In the current code, gk20a.h includes io.h which gets directly included

gk20a as a parameter leading to a circular dependency between io.h

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.

This change contains a generic cleanup of linux dependent parts of the
dbg_gpu_gk20a.* files. The following changes have been made
1) Moving methods into ioctl_dbg.* inside common/linux/
2) The structures dbg_session_gk20a and dbg_session_channel_data have
been split into two parts. struct device *dev is removed from
struct dbg_session_gk20a and instead packed into struct
dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into
ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and
remains in dbg_gpu_gk20a. Similarly, struct file is removed from
struct dbg_session_channel_data and is now packed into struct
dbg_session_channel_data_linux alongwith dbg_session_channel_data and
is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of
linux dependencies and remains in dbg_gpu_gk20a.
3) A callback function is added in order to release the
dbg_session_channel_data.

We currently bind only one channel to a debug session
But some use cases might need multiple channels bound
to same debug session
Add this support by adding a list of channels to debug session.
List structure is implemented as struct dbg_session_channel_data
List node dbg_s_list_node is currently defined in struct
dbg_session_gk20a. But this is inefficient when we need to
add debug session to multiple channels
Hence add new reference structure dbg_session_data to
store dbg_session pointer and list entry
For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create
two reference structure dbg_session_channel_data for channel
and dbg_session_data for debug session and bind them together
Define API nvgpu_dbg_gpu_get_session_channel() which will
get first channel in the list of debug session
Use this API wherever we refer to channel bound to debug
session
Remove dbg_sessions define in struct gk20a since it is
not being used anywhere
Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support
unbinding of channel from debug sesssion
