ARM: SAMSUNG: i2c/busses: Add HAVE_S3C2410_I2C option to include I2C for Samsung...

This patch adds HAVE_S3C2410_I2C to control inclusion of I2C bus driver
on Samsung SoCs and makes I2C bus driver dependency SoC specific instead
of machine specific. This will enalbe all machines using Samsung ARCH_S3C2410,
_S3C64XX, _S5P6440, _S5PC100, and _S5PV210 to select the I2C driver by default
