spi: mt65xx: Move pm_runtime_enable() call to remove all gotos
The last goto in the probe function can be removed by calling
pm_runtime_enable() right before devm_spi_register_master(), as
only some init checks were being performed after enabling pm.
This is a cleanup and brings no functional changes.
