Subject: [PATCH] pinctrl: pxa: pxa2xx: Remove 'pxa2xx_pinctrl_exit()' which is unused and broken

Commit 6d33ee7a0534 ("pinctrl: pxa: Use devm_pinctrl_register() for pinctrl registration")
has turned a 'pinctrl_register()' into 'devm_pinctrl_register()' in
'pxa2xx_pinctrl_init()'.
However, the corresponding 'pinctrl_unregister()' call in
'pxa2xx_pinctrl_exit()' has not been removed.

This is not an issue, because 'pxa2xx_pinctrl_exit()' is unused.
Remove it now to avoid some wondering in the future and save a few LoC.

If some some reason the function should be kept, at least it should be
only 'return 0;'
