pnv/xive: Allow mmio operations of any size on the ESB CI pages
We currently only allow 64-bit operations on the ESB CI pages. There's
no real reason for that limitation, skiboot/linux didn't need
more. However the hardware supports any size, so this patch relaxes
that restriction. It impacts both the ESB pages for "normal"
interrupts as well as the ESB pages for escalation interrupts defined
for the ENDs.
