It turns out that const and __{dev}initdata cannot be mixed currently
and that hpt366 host driver is also affected by the same issue:

This patch workarounds the problem by making static struct hpt_info instances
const.  Now all __devinitdata data in hpt366 host driver are read-only so it
builds again (driver's .init.data section gets marked as READONLY).

While at it:

* Bump driver version.
