[PATCH] of: address: mark 64-bit PCI resources explicitly as such

[Ahmad Fatoum]

Eventually, we shouldn't need this, when all code can deal with 64-bit
addresses. For now, PCI drivers, when given the choice between 32-bit
and 64-bit resources, should select the 32-bit one.

This patch makes the resources straight forward to compare.
