Remove drm_nouveau_private::fb member and map the piece of VRAM only when accessing VGA fonts. Collect copied code into the static function nouveau_vga_font_io().

From: Thierry Reding <treding at nvidia.com> This set of patches adds support for fences to Tegra DRM and complements the fence FD support for Nouveau. Technically this isn't necessary for a fence-based synchronization loop with Nouveau because the KMS core takes care of all that, but engines behind host1x can use the IOCTL extensions provided here to emit fence FDs that in turn can be

From: Chia-I Wu <olvaffe at gmail.com> [ Upstream commit efe2bf965522bf0796d413b47a2abbf81d471d6f ] This is motivated by having meaningful ftrace events, but it also fixes use cases where dma_fence_is_later is called, such as in sync_file_merge. In other drivers, fence creation and cmdbuf submission normally happen atomically, mutex_lock(); fence = dma_fence_create(..., ++timeline->seqno); submit_cmdbuf(); mutex_unlock(); and have no such issue. But in our driver, because most ioctls queue commands into ctrlq, we do not want to grab a lock. Instead, we set seqno to 0...
