Merge branch 'i2c/for-5.12' of git://git./linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:

 - mostly driver updates. Bigger ones for mlxcpld and iproc. But most of
   them are all over the place.

 - removal of the efm32, sirf, u300, and zte zx bus drivers because of
   platform removal. So, we have a pleasant diffstat this time.

 - first set of cleanups in the I2C core as preparation to increase
   maximum length of SMBus transfers to 255 (as specified in the new
   standard). Better documentation of struct i2c_msg and its flags stand
   out here.

 - the testunit can now respond to SMBus block process calls which is
   the testcase when implementing the above new maximum length.
