There is the only one user of the pxa2xx_set_spi_info(). Unexport it
and inline to the actual user.

It's not. What I meant is that you could use
platform_device_register_data() instead of the
"platform_device_alloc(); platform_data = info; platform_device_add();"
sequence.

It should be a safe conversion, but it's also fine to stay
with the existing version if you are worried about regressions.
