i2c: pxa: No need to set slave addr for i2c master mode reset
i2c: pxa: No need to set slave addr for i2c master mode reset

Normally i2c controller works as master, so slave addr is not needed, or
it will impact some slave device (eg. ST NFC chip) i2c accesses, because
it has the same i2c address with controller.

For example,
On the pxa1928 based platform, where PMIC (88pm860) is present @0x30
address on TWSI0 interface, and if we set 0x30 as a slave address in
pxa1928 TWSI0 module, all the transactions towards PMIC would go for toss.
