Now that everything is in place for modular io-pgtable formats,
allow the ARM LPAE and ARMV7S io-pgtable formats to be built
as modules, and allow the io-pgtable framework to be enabled,
without having to explicitly enable an io-pgtable format.

In preparation for modularizing io-pgtable formats, add support
for reference counting the io-pgtable format modules to ensure
that the modules are not unloaded while they are in use.
