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

This patch adds support for the Xilinx XPS IIC Bus Interface.

The driver uses the dynamic mode, supporting to put several
I2C messages in the FIFO to reduce the number of interrupts.

It has the same feature as ocores, it can be passed a list
of devices that will be added when the bus is probed.

As I2C interrupts must  be enabled for the MPC512x by the setup function
as well, "fsl,preserve-clocking" is handled in a slighly different way.
Also, the old settings are now reported calling dev_dbg(). For the
MPC512x the clock setup function of the MPC52xx can be re-used.
Furthermore, the Kconfig help has been updated and corrected.

LPC_SCH is selected by GPI_SCH and I2C_ISCH, even when PCI is not
enabled, but LPC_SCH depends on PCI, so make GPI_SCH and I2C_ISCH
also depend on PCI.

Those 2 selects also need to select what LPC_SCH selects,
since kconfig does not follow selects.

Now that we have ACPI-based SMBus controller drivers, and we will start
telling users to use them instead of native drivers when I/O resources
conflict, I think it would be good to clearly mark ACPI drivers as such
in Kconfig.

This is exactly the same as we just did for hwmon drivers.
