ASoC: SOF: Intel: bdw: Use generic function for fw ready / mem windows creation

Browse Source 
bdw_get_windows / bdw_fw_ready is identical with the generic
implementation introduced in a previous patch.

So remove bdw_get_windows / bdw_fw_ready and use the generic
sof_get_windows version.

Do not forget to implement get_mailbox_offset/get_window_offset
so that we export the correct mailbox/memory window offset to
the outside world.
