Coldfire targets: Restore EMAC status after using the EMAC for bitmap resizing. Fixes FS #10412. The tone and EQ filter calculation relies on the proper EMAC mode. EQ filters were not affected because they're set from a different thread, hence FS #10412 only affected the iAudios (coldfire + albumart + software tone controls).
