Implement support for 64kB large page size. Add an API to create an
address space via IOCTL so that we can accept flags, and assign one
flag for enabling 64kB large page size.
Also adds APIs to set per-context large page size. This is possible
only on Maxwell, so return error if caller tries to set large page
size on Kepler.
Default large page size is still 128kB.

Merge initialization code from gk20a_init_system_vm(),
gk20a_init_bar1_vm() and gk20a_vm_alloc_share() into gk20a_init_vm().
Remove redundant page size data, and move the page size fields to be
VM specific.

Alloc space writes the page size to a field that requires pgsz_idx.
That can cause corruption in internal kernel structures.
Clear_sparse treated a parameter as page size instead of index.

When clearing sparse buffers, pte->ref must be cleared once the PTE
is freed.

The code took reference to gk20a by using gk20a_busy_noresume(). This
function takes pm runtime reference only to the GPU, however, the code
dropped the reference by calling gk20a_idle() which also drops the
reference to the platform dependencies (host1x).
This patch modifies gm20b_mm_mmu_vpr_info_fetch_wait() to drop only
the GPU reference.

Gk20a unmaps the addresses binding to dummy page to clear sparse.
On Gm20b, we need to free the allocated page table entry for sparse
memory.
