pinctrl: nomadik: remove dead code after DB8540 pinctrl removal

Commit b6d09f7 ("pinctrl: nomadik: Drop U8540/9540 support") removes
the DB8540 pin controller driver and its config PINCTRL_DB8540.

There is some code left-over in the generic nomadik pinctrl driver, i.e.,
drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the
removed DB8540 pin controller driver.

Remove this remaining dead code.

This issue was discovered with ./scripts/checkkconfigsymbols.py.
