Constify .data in OF table and {palmas,tps65917}_irq_chip and replace
the variable *features->features in struct palmas_driver_data and
drop the {palmas,tps659038}_features variables and use their values
directly in the named initialization.

While at it, drop the inner leading commas for OF match table.

...and nothing here about the main advantage, i.e. constification of the data...
