The top registers initialization is very specific to the actual hardware used, even the way in which we read from and write to the top registers varies from chip to chip. This patch moves all top registers initialization to wl12xx. Also add a boot op for the wlcore module to call at the right time and a few callbacks with the common called to be called from the lower drivers boot operations.
