spi: export tracepoint symbols to modules
The newly added tracepoints in the spi-mxs driver cause a link
error when the driver is a loadable module:
ERROR: "__tracepoint_spi_transfer_stop" [drivers/spi/spi-mxs.ko] undefined!
ERROR: "__tracepoint_spi_transfer_start" [drivers/spi/spi-mxs.ko] undefined!
I'm not quite sure where to put the export statements, but
directly after the inclusion of the header seems as good as
any other place.
Fixes: f3fdea3af405 ("spi: mxs: add tracing to custom .transfer_one_message callback")
