Make of_device_id array const, because all OF functions
handle it as const.

Linus Torvalds 13509c3a9d Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c changes from Wolfram Sang:
 - new drivers for exynos5, bcm kona, and st micro
 - bigger overhauls for drivers mxs and rcar
 - typical driver bugfixes, cleanups, improvements
 - got rid of the superfluous 'driver' member in i2c_client struct This
   touches a few drivers in other subsystems.  All acked.

Maxime COQUELIN 85b4fab269 i2c: i2c-st: Add ST I2C controller
This patch adds support to SSC (Synchronous Serial Controller)
I2C driver. This IP also supports SPI protocol, but this is not
the aim of this driver.

This IP is embedded in all ST SoCs for Set-top box platorms, and
supports I2C Standard and Fast modes.
