Add staging board support for the KZM9D board and add
an emxx_udc platform device to allow in-tree continous
development of the driver on the KZM9D board.
When DT bindings are ready for the emxx_udc driver then
the platform device in the KZM9D staging board code can
easily be removed. Until then we use platform devices
to continously improve the driver and integration code.

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.
