Wolfram Sang 58637b3027 i2c: rcar: always clear ICSAR to avoid side effects ...

[ Upstream commit eb01597158ffb1853a7a7fc2c57d4c844640f75e ]

On R-Car Gen2, we get a timeout when reading from the address set in
ICSAR, even though the slave interface is disabled. Clearing it fixes
this situation. Note that Gen3 is not affected.

To reproduce: bind and undbind an I2C slave on some bus, run
'i2cdetect' on that bus.
