pinctrl: nomadik: make core support explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/pinctrl/nomadik/Kconfig:config PINCTRL_NOMADIK
drivers/pinctrl/nomadik/Kconfig: bool "Nomadik pin controller driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

We delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
