The platform_data irq_base is not being used it seems..

..but irq_base here is still in use as that's where the value from
irq_alloc_descs() is being stored to. So I'll drop the changes to
struct twl6040 from this patch as otherwise twl6040 code won't compile.

Turns out I did not have twl6040 selected in any of the testconfigs
that I ran.
