watchdog: ts72xx_wdt: constify watchdog_ops structure
Check for watchdog_ops structures that are only stored in the ops field of
a watchdog_device structure. This field is declared const, so watchdog_ops
structures that have this property can be declared as const also.
This issue was detected using Coccinelle and the following semantic patch:
@r

identifier i;
position p;

static struct watchdog_ops i@p = { ... };
@ok@
identifier r.i;
struct watchdog_device e;

e.ops = &i@p;
