pinctrl: changes hog mechanism to be self-referential

Instead of a specific boolean field to indicate if a map entry shall
be hogged, treat self-reference as an indication of desired hogging.
This drops one field off the map struct and has a nice Douglas R.
Hofstadter-feel to it.

 Since it may be common to request the core to hog a few always-applicable
 mux settings on the primary pin controller, there is a convenience macro for
 this:
 
-PIN_MAP_PRIMARY_SYS_HOG("POWERMAP", "power_func")
+PIN_MAP_PRIMARY_SYS_HOG("POWERMAP", "pinctrl-foo", "power_func")
 
 This gives the exact same result as the above construction.
