From: Arnd Bergmann <arnd@arndb.de>
All users of the legacy interface now select CONFIG_GPIOLIB_LEGACY,
so it can be turned off by default and only get built on platforms
that still have one unconverted driver.
Allow turning it on manually for compile testing, in order to keep
the build coverage of the legacy drivers in allmodconfig and
randconfig.

+ There are a few legacy platforms that use the traditional GPIO
+ number based interfaces instead of GPIO descriptors.
+ Say Y here to enable build testing drivers that are specific

+ If unsure, say N.
