gpu: nvgpu: remove os_fence dependency from channel_sync

Browse Source 
Move the wait_cmd_buffer programming for channel_sync->wait_fd to
channel_sync.c.  nvgpu_os_fence->program_waits
interface is now removed. channel_sync can directly retrieve
syncpt/semaphore from the interfaces of struct nvgpu_os_fence_syncpt
and struct nvgpu_os_fence_sema and use it for the wait programming.

Also, change int to u32 for some variables such as num_fences,
max_wait_size and wait_cmd_size.
