following compilation error are reported with CONFIG_DEBUG_FS=n:
pci.c:246:7: error: 'struct mm_gk20a' has no member named 'ltc_enabled'
pci.c:247:7: error: 'struct mm_gk20a' has no member named 'ltc_enabled_debug'
possible compilation error(reported sometime):
gk20a_allocator.c:1163:13: error: 'gk20a_alloc_debugfs_init' defined
but not used
fixed by adding '#ifdef CONFIG_DEBUG_FS' for debug only code.
following variables from gk20a.c are not initialized from
CONFIG_DEBUG_FS=n path, it will cause kernel oops when booting:
gk20a->mm.bypass_smmu = platform->bypass_smmu;
gk20a->mm.disable_bigpage = platform->disable_bigpage;
gk20a->mm.has_physical_mode = true;
fix it by move them out from '#ifdef CONFIG_DEBUG_FS' section.

To be able to scan, PCI devnodes need to be in a directory with read
permission. By default /dev is read protected by SELinux policy. Move
the devnodes to their own directory so that reading this one
directory can be allowed.
At the same time rename the nodes to start with string "card-".

Watchdog timeout is now zero for PCIe devices. This makes also
semaphore acquire timeout to be zero. Fix the timeout to be the
same as for platform devices.
