Title:
  Support setting I2C_TIMEOUT via ioctl for i2c-designware

Status in HWE Next:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  SRU Justification

  [Impact]
  The timeout value in i2c-designware is hardcoded. Userspace tool may want to 
change the timeout value via ioctl I2C_TIMEOUT, but it doesn't work for 
i2c-designware.

  [Test Case]
  Change the timeout value via ioctl I2C_TIMEOUT. Nothing happened.
  With the patch, timeout value for i2c-designware will be updated correctly.

  [Regression Potential]
  Minimal. The change only applies to a specific driver, i2c-designware. Also, 
it has minimal code change.
