No, specifying it via the device tree was subsequently added with
commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data"),
sorry for not mentioning this in the commit message.

There's already a bool in struct spi_master for this functionality and
device tree support for pl022, so I don't quite understand why converting
the bool to an int and adding device tree support for bcm2835 would be
the wrong approach?
