[PATCH 1/2] staging: olpc_dcon: check for CONFIG_OLPC before calling olpc_board_at_least()

[Murilo Opsfelder Araujo <mopsfelder@gmail.com>]

The following error messages are thrown by sparse when CONFIG_OLPC is
not defined:

drivers/staging/olpc_dcon/olpc_dcon.c:147:17: error: undefined identifier 'olpc_board_at_least'
drivers/staging/olpc_dcon/olpc_dcon.c:208:14: error: undefined identifier 'olpc_board_at_least'

This patch fixes these errors.
