powerpc/mpic: Create a revmap with enough entries for IPIs and timers
The current mpic code creates a linear revmap just big enough for all the sources, which happens to miss the IPIs and timers on some machines. This will in turn break when the irqdomain code loses the fallback of doing a linear search when the revmap fails (and really slows down IPIs otherwise). This happens for example on the U4 based Apple machines such as the dual core PowerMac G5s. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
