[POWERPC] Add workaround for MPICs with broken register reads
Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
