[PATCH RESENDv2] mach:-s3c64xx:Output trace information with WARN_ON if calls for setting up gpio board configuration fail in s3c64xx_i2s_cfg_gpio

[xerofoify@gmail.com (Nicholas Krause)]

This fixes the function s3c64xx_i2c_cfg_gpio to log output to the 
kernel log buff with WARN_ON if any of the calls to either 
s3c_gpio_cfgpin_range or s3c_gpio_cfgpin fail as we cannot exit 
from s3c64xx_i2s_cfg_gpio if any of these calls fail due to 
other intended function work being required to complete. Therefore
due to this output our failed calls by means of WARN_ON to the
kernel log buffer for failed configuration of gpio devices using
this driver file.
v2:Fix Patch Wording as it was clearly confusing and incorrect
