48 bit ppgtt device configuration is really just extended address
range full ppgtt and may actually be something other than 48 bits.
Change HAS_FULL_48BIT_PPGTT() to HAS_4LVL_PPGTT() to better
describe that a 4 level walk table extended range PPGTT is being
used. Add a new device info field that specifies the number of
bits to prepare for cases where the range is not 32 or 48 bits.
Also rename other functions and comments from 48bit to 4-level.
Making use of the device info address range for gen6 highlights
simularities in the gen6 and gen8 code paths so move the common
code in to a common function.
v2: Keep HAS_FULL_PPGTT() unchanged (Chris)
v3: Simplify condition in gen8_ppgtt_create() (Chris)
Remove unnecessary line coninuations (Bob)
Rename functions/defines/comments from 48bit to 4lvl (Rodrigo/Bob)
v4: Rename FULL_4LVL_PPGTT to simply 4LVL_PPGTT (Rodrigo)
Be explised in setting vm.total to 1ULL << 32 (Rodrigo)
Gen 7 is 31 bits, not 32 (Chris)
v5: Mock device is 64b(63b) not 48b (Chris)
v6: Rebase to latest drm-tip (Bob)
v7: Combine common code for gen6/gen8 ppgtt create (Chris)
Improve comment on device info field (Chris)
v8: gvt is actually full ppgtt (both 3-lvl and 4-lvl) so name cap
define appropriately (Chris)
v9: rebase on latest
v10: fix missed vgpu change of FULL_48BIT to FULL in CAPS define (Bob)
