pinctrl: sirf: make atlas7 explicitly non-modular

The Makefile currently controlling compilation of this code is:

drivers/pinctrl/sirf/pinctrl-atlas7.o
---> drivers/pinctrl/sirf/Makefile:obj-y += pinctrl-atlas7.o

...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.
