bhnd(4): Fix bcma/siba core reset behavior
Add missing support for specifying I/O control flags during core reset,
and resolve a number of siba(4)-specific reset issues:
- Add missing check for target reject flags in siba_is_hw_suspended().
- Remove incorrect wait on SIBA_TMH_BUSY when modifying any target state
register; this should only be done when waiting for initiated
transactions to clear.
- Add missing wait on SIBA_IM_BY when asserting SIBA_IM_RJ.
- Overwrite any previously set SIBA_TML_REJ flag when bringing the core
out of reset. This fixes a lockup that occured when we brought up a core
(after reboot) that had previously been placed into RESET by siba_bwn(4).
