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).
