[Skiboot] [PATCH] devicetree: Remove lpc interrupt properties

[Reza Arbab]

After commit 7b12d5489fcf ("hw/lpc: Configure SerIRQ interrupts on
P9P"), we abort on p9p Simics:

[ 1486.000029845,3] Duplicate property "interrupt-map" in node /lpcm-opb at 6030000000000/lpc at f0000000
[ 1487.000158147,0] Aborting!

Since skiboot creates these interrupt properties now, and always has on
older p9 systems, remove them from the input device tree.
