This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.
The microcode_core.c patch was provided by Stephen Rothwell
<sfr@canb.auug.org.au> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

One of the Tegra I2C blocks is inside the DVC (Digital Voltage Controller)
block. This block is identical to the rest of the I2C blocks, except that
it only supports master mode, it has registers moved around, and it needs
some extra init to get it into I2C mode. The register moves are handled
by i2c_readl and i2c_writel
This patch adds a new compatible value for controllers of this "DVC"
type; I figured that this approach was reasonable, as opposed to adding
an is-dvc property under the existing compatible value, since the HW
truly is different.
v2: Call of_device_is_compatible() to determine is_dvc, instead of storing
the flag in tegra_i2c_of_match[]'s .data field.

Before registering an adapter to i2c subsystem, we need make sure
driver is ready for incoming i2c xfer, becasue the i2c_add_adapter()
may trigger a i2c device driver's proble function which may start
some real i2c xfer. I met this issue when integrating a TSC2007 i2c
touch screen device with the i2c-eg20t driver.
This patch will call request_irq() and hw init before calling
i2c_add_adapter().

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined
in the platform data of the i2c device. When DT is not enabled,
the above function always returns -EINVAL. Since there can be
some i2c devices which don't need to configure any gpio lines,
the probe of such devices would fail here. Changing the default
return value to success would fix this issue.

This converts the remaining USB drivers in the kernel to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

Double the timeout in the loop which busy-waits for the "master-done"
bit to be set. This bit indicates whether an i2c transaction has
completed; on the DB1300 and DB1550 boards this timeout is slightly
too short and causes transactions to the WM8731 codec to be falsely flagged
as failed. The timeout itself is necessary since transactions to
non-existant slaves never set this bit in the first place (and cause
i2cdetect to hang).
With this change the WM8731 codec on the DB1300/DB1550 boards is correctly
detected and initialized.

Move all register manipulation code into the core, also move register
offset definitions to i2c-designware-core.c since the bus specific
portions of the driver no longer need/use them.

Add check to make sure that the core is enabled and has outstanding
interrupts. The activity bit is masked due to the fact that it will
stay active even after the controller has been disabled until the
contoller internal state machines have settled.

With multiple I2C adapters possible in the system each running at
(possibly) different speeds we need to move the controller
configuration bit field to the adapter.

The functionality of the adapter depends on the configuration of the
IP block at silicon compile time and is adapter specific.

The clock frequecy supplied to the IP core is specific to a single
instance of the driver. This patch makes it possible to have multiple
Designware I2C cores in the system possibly running at different core
frequencies.
