spi: designware: Change include order

With current order of include files, the file designware_spi.c
can't see that the struct global_data has the member
board_type when CONFIG_BOARD_TYPES is defined. By not seeing this
then all the members are shifted in the struct global_data.
So when the driver is trying to read from device tree blob, it
would pass the wrong address to the function 'fdtdev_get_int'.
This will make to use the default frequency 500000.

The fix consists of changing the order of include files in
designware_spi.c to include first common.h file.
