channel_gk20a is clear from chip specifics and from most dependencies,
so move it under the common directory.

Add READ_SM_ERROR IOCTL support to TSG level.
Moved the struct to save the sm_error details
from gr to tsg as the sm_error support is context
based, not global.
Also corrected MISRA 21.1 error in header file.
nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and
nvgpu_dbg_gpu_ioctl_read_single_sm_error_state
functions are modified to use the tsg struct
nvgpu_tsg_sm_error_state.

This change frees tsg_private structure in nvgpu_ioctl_tsg_open() when
gk20a_busy() fails and avoids a memory leak.

The nvgpu_ioctl_tsg_open() does not make sure that GPU is
unpowergated. Due to this it leads to kernel
panic when GPU registers are accessed when powergated.

Move all Linux source code files to drivers/gpu/nvgpu/os/linux from
drivers/gpu/nvgpu/common/linux. This changes the meaning of common
to be OS independent.
