wl12xx/wlcore: initial split of probe We need to set some parameters (eg. partition and register tables) during probe of the lower driver, so split the probe function, leaving most of it in wlcore, but moving the hw struct allocation to the lower driver.

wlcore/wl12xx: move top initialization to wl12xx 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.

wlcore/wl12xx: add hw op for getting rx buffer data alignment An aligned data buffer is such where the Ethernet portion of the packet starts on a 4-byte boundary. Some chip families support padding the Rx data buffer to achieve such alignment, others rely on the host to perform it. Implement the HW op for getting alignment state in wl12xx.

wl18xx: sane defaults for HT capabilities Introduce a default set of HT capabilities that are set according to the number of antennas on the board. Move the HT setting code down to allow the number of antennas to be set (and optionally overridden) before it. Remove the "mimo" HT option, since the default mode now enables MIMO is possible. Use this opportunity to add a helper function for setting HT capabilities and reduce the volume of the code a bit.
