Mon Oct 11 04:15:48 EDT 2010
S5PV310 and S5PC210 support more I2C devices than previous SoCs.
Add the device support code for them.

Changes since V2:
- removed some s5p reference leftovers from V1
- adapted setup-i2cX.c to use s3c_gpio_cfgall_range()
- added missing entries in plat-samsung/include/plat/devs.h
- added missing 'select HAVE_S3C2410_I2C' in KConfig
