powerpc/microwatt: Add mmu bits to device tree
In commit 5402e239d09f ("powerpc/64s: Get LPID bit width from device
tree") the kernel tried to determine the pid and lpid bits from the
device tree. If they are not found, there is a fallback, but Microwatt
wasn't covered as it has the unusual configuration of being both !HV and
bare metal.
Set the values in the device tree to avoid having to add a special case.
The lpid value is the only one required, but add both for completeness.
