Subject: [PATCH v3 00/14] i2c-octeon and i2c-thunderx drivers

This series for the Octeon i2c driver is an attempt to upstream some
bug fixes and features that accumulated for some time.

On top of the Octeon changes a i2c driver for the ThunderX SOC is
added which uses the same functional block as the Octeon driver.

Patches #1-3 are cleanups.
Patches #4-11 are forward-ports of Octeon features and bugfixes.
Patch #12 prepares for the driver split
Patches #13-14 add the ThunderX driver.

Patches are on top of 4.5-rc7 and were tested on OCTEON, OCTEON-78
and ThunderX.

Changes to v2:
- Split clenaup patch into several patches
- Strictly moved functional changes to later patches
- Fixed do-while checkpatch errors
- Moved defines to the patches that use them
- Use BIT_ULL macro
- Split ThunderX patch into 2 patches

Changes to v1:
- Fixed compile error on x86_64
- Disabled thunderx driver on MIPS
- Re-ordered some thunderx probe functions for readability
- Fix missing of_irq.h and i2c-smbus.h includes
- Use IS_ENABLED for CONFIG options
