It turns out that const and __{dev}initdata cannot be mixed currently.

This patch workarounds the problem by removing __devinitdata tag from 'primary'
variable (which makes 'primary' to be moved from .init.data to .bss section).
Now all __devinitdata data in cy82c693 host driver are read-only so it builds
again (driver's .init.data section gets marked as READONLY).

While at it:

* Move 'primary' variable to its only user, init_iops_cy82c693().

* Bump driver version.
