Currently, the driver probing fails when client->irq is 0 (which means "no interrupt"). Don't register the interrupt handler in that case but successfully finish the device probing instead.

The driver has a I2C device id table that is used to create the modaliases
and already contains a "ltc3589" device id. So the modalias is unnecessary.

VCCR is used as a trigger to start voltage transitions, so
we need to mark it volatile in order to make sure it gets
written to hardware every time we set a new voltage.

Fixes regulator voltage being stuck at the first voltage
set after driver load.

When fixed_uV is set and n_voltage is 1, regulator core will return
rdev->desc->fixed_uV in regulator_get_voltage() and regulator_list_voltage().

Rename ltc3589_standby_regulator_ops to ltc3589_fixed_standby_regulator_ops,
this makes the code clear that the ops is for fixed voltage regulator.
