soc: atmel_sam: Add _INST to ATMEL_SAM_DT_PIN* macros

Browse source 
The macros are used to get the pin(s) of a given driver instance. Add
_INST prefix to match convention used by the devicetree.h. The original
macros can now be used to obtain pin(s) of an arbitrary device instance
identified by the nodelabel.
