[PATCH 21/27] ARM: SAMSUNG: Add s3c_gpio_cfgrange_nopull() helper

From: Ben Dooks <ben-linux at fluff.org>

A number of the SDHCI code configure a GPIO to a special function
and remove any pull-up, so add s3c_gpio_cfgrange_nopull() as a
wrapper to the s3c_gpio_cfgall_range() to make the code that
calls it fit on one line.
