spi/bcm63xx: Move default clock configuration to kill compiler warning
drivers/spi/spi-bcm63xx.c: In function ‘bcm63xx_spi_setup_transfer’:
drivers/spi/spi-bcm63xx.c:207: warning: ‘clk_cfg’ may be used uninitialized in this function
While this is a false positive, it can easily be avoided by selecting
the default clock configuration first.
