pinctrl: add includes and ifdefs for non-DT builds

Commit e81c8f18af
"pinctrl: pinconf-generic: add generic APIs for mapping pinctrl node"
Added function prototypes with implicit dependencies
on other header files causing build warnings like this:

warning: 'struct device_node' declared inside parameter list [enabled
by default]
   unsigned *num_maps);
   ^
Let's just add ifdefs for non-DT systems (the actual code is
already ifdefed) and #include <linux/device.h> to get the
most important structs and forward-declare the pinctrl
core structs.
