libnvdimm: Move attribute groups to device type

Statically initialize the attribute groups for each libnvdimm
device_type. This is a preparation step for removing unnecessary exports
of attributes that can be included in the device_type by default.

Also take the opportunity to mark 'struct device_type' instances const.

libnvdimm/namespace: Differentiate between probe mapping and runtime mapping

The nvdimm core currently maps the full namespace to an ioremap range
while probing the namespace mode. This can result in probe failures on
architectures that have limited ioremap space.

For example, with a large btt namespace that consumes most of I/O remap
range, depending on the sequence of namespace initialization, the user
can find a pfn namespace initialization failure due to unavailable I/O
remap space which nvdimm core uses for temporary mapping.

nvdimm core can avoid this failure by only mapping the reserved info
block area to check for pfn superblock type and map the full namespace
resource only before using the namespace.

Given that personalities like BTT can be layered on top of any namespace
type create a generic form of devm_nsio_enable (devm_namespace_enable)
and use it inside the per-personality attach routines. Now
devm_namespace_enable() is always paired with disable unless the mapping
is going to be used for long term runtime access.

libnvdimm/region: Rewrite _probe_success() to _advance_seeds()

The nd_region_probe_success() helper collides seed management with
nvdimm->busy tracking. Given the 'busy' increment is handled internal to the
nd_region driver 'probe' path move the decrement to the 'remove' path.
With that cleanup the routine can be renamed to the more descriptive
nd_region_advance_seeds().

The change is prompted by an incoming need to optionally advance the
seeds on other events besides 'probe' success.
