staging: board: Initial board staging support
Add staging board base support to allow continuous upstream
in-tree development and integration of platform devices.
Helps developers integrate devices as platform devices for
device drivers that only provide platform device bindings.
This in turn allows for incremental development of both
hardware feature support and DT binding work in parallel.
Two separate pieces of board staging functionality is
provided to ease per-board staging board support:
- The board_staging() macro allows easy per-board callbacks
- The board_staging_dt_node_available() provides DT node checking
Tested on the KZM9D board with the emxx_udc staging driver.

staging: comedi: ni_stc.h: remove stc read/write callbacks from ni_private
The drivers that include ni_mio_common.c set the stc register read/write
callbacks to private functions that handle the read/write operations in
the correct manner for the hardware.
The ni_atmio and ni_mio_cs drivers use identical code to handle the
operations.
The ni_pcimio driver is a bit different due to the non-windowed setup
of the stc registers on the m series boards. For the other boards
supported by the ni_pcimio driver, the direct access of the first 8
STC registers is also disabled due to a difference on the 611x devices.
These differences can all be handled in the ni_stc_{read,write}[lw]()
helpers. Refactor the helpers and remove the callbacks from the private
data.
Also, move the helper functions the handle the mapping of the windowed
STC register offsets to M series register offset from ni_pcimio.c to
ni_mio_common.c.

This macro is used to create the private data structure that is used by
the ni_atmio, ni_mio_cs, and ni_pcimio drivers. These drivers all include
the ni_mio_common.c source to provide most of the driver functionality.
The only driver specific information needed to convert the macro into a
proper struct definition is the MAX_N_CALDACS define. This define is used
to size a couple array members in the struct. The ni_atmio and ni_mio_cs
drivers both define MAX_N_CALDACS as 32. The ni_pcimio driver defines it
as (16+16+2). The ni_mio_common file only uses this define to sanity check
that the struct members are large enough for the number of channels in
the calibration subdevice.
Move the MAX_N_CALDACS define to ni_stc.h and set it to the largest number
of caldacs (34).
The ni_atmio and ni_mio_cs drivers also add one additional member to the
private data struct before using the NI_PRIVATE_COMMON macro.
For the ni_atmio driver, the struct pnp_dev pointer can be saved in the
comedi_device as the 'hw_dev'. The (*detach) of this driver can then use
to_pnp_dev() to get it back when detaching the pnp device.
In the ni_mio_cs driver, the struct pcmia_device pointer is not used so
it can simply be removed.
The NI_PRIVATE_COMMON macro can then be converted into a proper struct
definition.
