Pull i2c updates from Wilfram Sang:
 "I2C has the following updates for you:

   - an immutable cross-subsystem branch fixing PMIC access on Intel
     Baytrail

   - bigger driver updates to the designware, meson, exynos5 drivers

   - new i2c_acpi_new_device() function to create devices from ACPI

   - struct i2c_driver has now a flag 'disable_i2c_core_irq_mapping' to
     allow custom IRQ mapping in case the default does not fit

   - mux subsystem centralized error messages in its core

   - new driver for ltc4306 i2c mux

   - usual set of small updates"
