[PATCH 1/7] i2c/pxa2xx: Don't touch ISAR if not in slave mode

[Sebastian Andrzej Siewior]

The reset functions sets writes the slave address even in not slave
mode. I don't see any reason in writting it if slave mode is not
enabled.
I have here a PXA-I2C variant where this register is not availbale and
as such can not be touched.
