gpu: nvgpu: fix issue with CONFIG_DEBUG_FS=n

Browse Source 
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.
