i2c: pmcmsp: constify i2c_algorithm and i2c_adapter_quirks structures

Check for i2c_algorithm and i2c_adapter_quirks structures that are only stored in the algo and quirks fields of an i2c_adapter structure correspondingly. These fields are declared const, so i2c_algorithm and i2c_adapter_quirks structures that have this property can be declared as const also.

Theses issues were detected using Coccinelle and the following semantic patch:

@r disable optional_qualifier@
identifier i;
position p;
@@
static struct i2c_algorithm i@p = { ... };

@ok@
identifier r.i;
struct i2c_adapter e;
position p;
@@
e.algo = &i@p;

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

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
struct i2c_algorithm i = { ... };

The semantic patch for i2c_adapter_quirks is analogous.
