[PATCH 11/21] media: em28xx: add special case for legacy gpiolib interface

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The em28xx driver uses the old-style gpio_request_one() inteface to
switch the lna on the PCTV 290E card.

This interface is becoming optional and should no longer be called by
portable drivers. As I could not figure out an obvious replacement,
select the new GPIOLIB_LEGACY symbol as a workaround.
