spi/s3c64xx: Add missing pm_runtime_set_active() call in probe()

Browse source 
Mark device as PM runtime active during initialization to reflect
actual device power/clocks state. This reduces the enable count for SPI
bus controller gate clock so it can be disabled when the bus controller
is not used.
