Samsung device updates

[Ben Dooks]

Cleanups of the i2c device system, and helper code for setting platform
data.

Note, not run-tested yet, only buildtested across all defconfigs

[PATCH 1/9] ARM: SAMSUNG: Default s3c_device_i2c1

[Ben Dooks]

There are no current SoCs where i2c1 is anything other than an s3c2440-i2c
implementation, so change the device's name to be s3c2440-i2c so we can
go and eliminate the calls in the cpu-init which set the name.

[PATCH 2/9] ARM: SAMSUNG: Remove s3c_i2c1_setname() calls for s3c2440-i2c

[Ben Dooks]

Now we've defaulted the s3c_device_i2c1's name to s3c2440-i2c, remove
all the s3c_i2c1_setname("s3c2440-i2c") as they are no longer needed.

[PATCH 3/9] ARM: SAMSUNG: Default s3c_device_i2c2 to s3c2440-i2c

[Ben Dooks]

There are no current SoCs where i2c2 is anything other than a s3c2440-i2c
implementation (see also e4c5cb3796155eb4f15f7f0b1b7ea705f87743a7) so
change the device's name to s3c2440-i2c by default so we can eliminate
the calls that set the name.

Also remove the singler user of this, the s5pv210.

block, so change the default name to s3c2440-i2c and rename the
cases where it is s3c2410.

[PATCH 5/9] ARM: SAMSUNG: Eliminate s3c2440-i2c renames

[Ben Dooks]

Commit 0445af6624016110d1b448e0089261548ba29ee3 set the default
name to s3c2440-i2c, so we no longer need to do anything about
renaming it. Remove all the call sites and the header that was
included to get it.

[PATCH 6/9] ARM: SAMSUNG: Add helper to clone and set platform data

[Ben Dooks]

Add a helper to clone the platform data via kmemdup() and set it into
the specified device and report any problems via printk().

This is intended to replace a number of sites in the Samsung kernel
where the same thing is being repeated in specific platform setting
code. See next patches for replacements.

[PATCH 8/9] ARM: S3C24XX: Use s3c_set_platdata() helper

[Ben Dooks]

Commit f8b5ea089d5a447a8933a6540ceeccbcb78f9e53 added a helper
to copy and set platform data, so let's replace the various sites
in the Samsung support where this is happening.
