usb: musb: constify musb_hdrc_config structures
Declare musb_hdrc_config structures as const as they are only stored in
the config field of a musb_hdrc_platform_data structure. This field is of
type const, so musb_hdrc_config structures having this property can be
made const too.
Done using Coccinelle:
@r disable optional_qualifier@
identifier x;
position p;

static struct musb_hdrc_config x@p={...};
@ok@
struct musb_hdrc_platform_data pdata;
identifier r.x;

pdata.config=&x@p;
@bad@
position p != {r.p,ok.p};
