spi: dw: Remove unused dw_spi_cleanup function
The dw_spi_cleanup() function was removed by commit c63f5da00845
"spi: dw: Don't call kfree for memory allocated by devm_kzalloc".
commit ec37e8e1f0e3 "spi: dw: migrate to generic queue infrastructure" added
dw_spi_cleanup() but never use it. So now I got below build warning:
CC [M] drivers/spi/spi-dw.o
drivers/spi/spi-dw.c:609:13: warning: 'dw_spi_cleanup' defined but not used [-Wunused-function]
