Coldfire: Fix the modification of IMR. Interrupts must be masked at the core level at at least the level of the interrupt being masked. Not following the datasheet and relying strictly on and/or_l causes unhandled 'Levelx' exceptions (showing itself quite often in PCM mixer work which more greatly stresses PCM lockout).
