Subject: [PATCH 22/36] ARM: s3c: leds: move setpull() calls into board files
The leds-s3c24xx driver calls the private s3c_gpio_setpull()
interface for each gpio line, but doing this requires
access to the machine header files.
Move those calls into the machine init functions for any
board that uses the driver.
