Edward O'Callaghan	3e67cb7b78	raiden_debug_spi.c: Add a delay following AP/EC flash enable ... Add a delay following the AP and EC flash enable requests. This allows any power rails enabled by these signals to settle and to meet the power on to first SPI write timing requirements.

Edward O'Callaghan	2141250162	raiden_debug_spi.c: Implement retry mechanism ... This overcomes a problem with the ServoMicro where USB packets can be ack'd by the device without triggering interrupts or loading data into the USB endpoints. The retry mechanism attempts the USB read 3 times before reattempting the write call to avoid performing multiple SPI transfers due to a USB problem. This process repeats 3 times before we return the last error code. Intermediary problems are reported in the status code.
