cmake: prefer cache BOARD_IDENTIFIER over extracting from BOARD

Browse Source 
The BOARD_IDENTIFIER is extracted from the BOARD argument provided by
the user.

Thereafter the BOARD_IDENTIFIER is compared to the list of valid board
identifiers returned by list_boards.py, and expanded with optional
fields as required.

Thereafter the expanded and full BOARD_IDENTIFIER is place as internal
variable in the CMake cache.

This means subsequent CMake invocations should use the expanded
BOARD_IDENTIFIER from the CMake cache instead of extracting it from the
BOARD variable.
