For a hardware project, I need the I2C master of SiLabs' CP2615 chip
to be visible from under Linux. This patchset adds i2c-cp2615, a
driver which sets up an i2c_adapter for said chip.

Changes in v3:
* Fixed SPDX header
* Added I2C_AQ_NO_REP_START adapter quirk to i2c.h
* Added I2C_AQ_NO_ZERO_LEN | I2C_AQ_NO_REP_START to CP2615's quirk flags
* Made the driver only bind to the IOP interface
* Return -ENXIO instead of -ECOMM when the device does not ACK
* Formatting, fix almost all warnings and checks from `checkpatch --strict`
  * CamelCase checks remain. These identifiers were taken from SiLabs'
    Application Note, I thought it made sense to preserve these as-is.
