mfd: sm501: Constify gpio_chip structures

These structures are only used to copy into other structures, so declare
them as const.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable optional_qualifier@
identifier i;

static struct gpio_chip i@p = { ... };

@bad@
position p != {r.p,ok.p};
