The simulator ring buffer DMA interface supports buffers of the following sizes:
4, 8, 12 and 16K. At present, it is configured to 4K and it happens to match
with the kernel PAGE_SIZE, which is used to wrap back the GET/PUT pointers once
4K is reached. However, this is not always true; for instance, take 64K pages.
Hence, replace PAGE_SIZE with SIM_BFR_SIZE.
Introduce macro NVGPU_CPU_PAGE_SIZE which aliases to PAGE_SIZE and replace
latter with former.

max_ctxsw_ring_buffer_size variable in struct nvgpu_gr is used to store
max ring buffer size which is then referred into linux specific code
We only use macro GK20A_CTXSW_TRACE_MAX_VM_RING_SIZE to initialize
the variable.
And max_ctxsw_ring_buffer_size does not belong to nvgpu_gr struct
anyways
Considering above remove max_ctxsw_ring_buffer_size from nvgpu_gr and
use macro directly in linux specific code

We have 3 header files for FECS tracing support
include/nvgpu/gr/fecs_trace.h : common header
include/nvgpu/ctxsw_trace.h : header that includes both common and
os-specific functions
os/linux/ctxsw_trace.h : linux specific header
Remove the second header since it is not needed.
Move all structures that are needed in common code to
include/nvgpu/gr/fecs_trace.h
Move all function declarations that are needed in common code to
include/nvgpu/gr/fecs_trace.h
Move all linux specific declarations in os/linux/ctxsw_trace.h and
rename this file as os/linux/fecs_trace_linux.h
Also rename os/linux/ctxsw_trace.c to os/linux/fecs_trace_linux.c
