gpu: nvgpu: sync_framework cleanups
This patch deals with cleanups meant to make things simpler for the upcoming os abstraction patches for the sync framework. This patch causes some substantial changes which are listed out as follows. 1) sync_timeline is moved out of gk20a_fence into struct nvgpu_channel_linux. New function pointers are created to facilitate os independent methods for enabling/disabling timeline and are now named as os_fence_framework. These function pointers are located in the struct os_channel under struct gk20a. 2) construction of the channel_sync require nvgpu_finalize_poweron_linux() to be invoked before invocations to nvgpu_init_mm_ce_context(). Hence, these methods are now moved away from gk20a_finalize_poweron() and invoked after nvgpu_finalize_poweron_linux(). 3) sync_fence creation is now delinked from fence construction and move to the channel_sync_gk20a's channel_incr methods. These sync_fences are mainly associated with post_fences. 4) In case userspace requires the sync_fences to be constructed, we try to obtain an fd before the gk20a_channel_submit_gpfifo() instead of trying to do that later. This is used to avoid potential after effects of duplicate work submission due to failure to obtain an unused fd.
