pinctrl: disallow map table entries with NULL dev_name field
Hog entries are mapping table entries with .ctrl_dev_name == .dev_name.
All other mapping table entries need .dev_name set so that they will
match some pinctrl_get() call. All extant PIN_MAP*() macros set
.dev_name.
So, there is no reason to allow mapping table entries without .dev_name
set. Update the code and documentation to disallow this.
