spi: spi-davinci: Fix variable type
'prescale' contains the return value of davinci_spi_get_prescale() which is a signed integer. Convert 'prescale' to integer to silence the following warning: drivers/spi/spi-davinci.c:318 davinci_spi_setup_transfer() warn: unsigned 'prescale' is never less than zero.
