i2c-s3c2410: Don't return error if no gpio entry in Device Tree blobsamsung-lt-v3.2-rc6-1
There can be some i2c devices which don't need to configure any
gpio lines. s3c24xx_i2c_parse_dt_gpio doesn't handle the case where
there is no gpio entry in the device tree blob.
Added specific check to handle -ENOENT case.
