char: ipmi: constify ipmi_smi_handlers structures

Declare ipmi_smi_handlers structures as const as they are only passed as
an argument to the function ipmi_register_smi. This argument is of type
const, so ipmi_smi_handlers structures having similar properties can be
declared const too.
Done using Coccinelle:

@r1 disable optional_qualifier@
identifier i;
position p;

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

@ok1@
identifier r1.i;
position p;
