[RFC][PATCH 1/3] spi: let master a chance to setup device before registering it

[Paul Fertser]

Call setup() before registering the device because registering leads
to a probe routine of the slave device and that requires an
initialised master.

TBH, i do not fully understand the framework, so this and the following patches
might be rather wrong. But the issues i tried to fix were real indeed :)
