staging: olpc_dcon: move more variables into dcon_priv
This moves dcon_source and dcon_pending into the dcon_priv struct.
Because these variables are used by the IRQ handler (which is
registered in the model-specific callbacks), we end up needing
to move dcon_priv into olpc_dcon.h. This also changes the IRQ
registration to use the dcon_priv pointer as dev_id, instead of
dcon_driver.
