this removes workaround for spurious interrupts added in r26316
side effect: make keyclicks work correctly when used intensively (with
the scrollwheel for example), the clicks should be inserted fast enough
for the PCM fifo to not become empty.
PL190 can cause spurious interrupts if an interrupt is triggered by a
peripheral shortly before the interrupt for this peripheral is cleared
from VIC registers.
As an effect we should only write in VIC_INT_EN_CLEAR after having
disabled the source of the interrupt in the peripheral.

Even if we disable it in VIC_INT_EN_CLEAR, it still fires an interrupt

Locking requires disabling interrupts completely.
I'm not sure if DMAC is the only interrupt affected or if we can't rely

If it's the latter, we will need to have special locking scheme for
