Simon Glass bddac45d04 pinctrl: Return -ENOSYS when system call is not available
Update the code to use -ENOSYS, which is the correct error code for an
unimplemented system call in U-Boot.

Also we should not check for a missing operations array as this is not
permitted. For now this can be covered by an assert().
