Subject[PATCH 3/4] introduce __devinitconst
The drivers picked just serve as examples (which I routinely build and
hence am able to easily verify), i.e. as before he patch doesn't change
all instances where 'const' could have been added as a result of the
base change, only where the change has a real effect (the module loader
doesn't enforce read-only section attributes at present, so only
built-in files make a real difference).

For the PCI ID tables a change like this could probably be done almost
globally in drivers/.

The cleaning up of all the invalid uses of 'const' and '__devinitdata'
on the same object could likewise be done in an almost global fashion,
although drivers/ide/pci/ seems to be the most significant violator.
