From: George Kashperko <george@xxxxxxxxxxx>
Major differences between AI/SB from drivers' perespective is control
and state flags handling. These long term used to be TMSLOW/TMSHIGH ones
and in order to be handled transparently should be abstracted by some
indirect access handlers. This patch forces use of ssb_core_ctl_flags
and ssb_core_state_flags introduced earlier. TMSLOW/TMSHIGH defines outside
ssb code (b43, ssb gige and ohci drivers) were renamed to reflect actual
meaning, flags' definitions moved to low two bytes. Common TMSLOW/TMSHIGH
defines moved to ssb_private.h in order to limit their use by internal
SB-specic code only.
