[PATCH 09/21] input: gpio-keys: make legacy gpiolib optional

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

Most users of gpio-keys and gpio-keys-polled use modern gpiolib
interfaces, but there are still number of ancient sh, arm32 and x86
machines that have never been converted.

Add an #ifdef block for the parts of the driver that are only
used on those legacy machines.
