spi/ath79: add delay between SCK changes The driver uses the "as fast as it can" approach to drive the SCK signal. However this does not work with certain low speed SPI chips (e.g. the PCF2123 RTC chip). The patch adds per-bit slowdowns in order to be able to use the driver with such chips as well.
