can: flexcan: flexcan_probe(): make regulator xceiver optional

Browse source

As the transcevier regulator is optional, this patch switches from
devm_regulator_get() to devm_regulator_get_optional(). This gets rid of "using
dummy regulator" warning message from the regulator core, if no regulator is
available.
