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.

v1->v2:
 * Moved the OF table just above its user.
 * Removed trailing comma from the terminator entry for the OF table.

OK, will send v3, if there is no other comments.
