[PATCH v12 1/6] fpga: Add flag to indicate SPI bitstream is bit-reversed

From: Anatolij Gustschin Add a flag that is passed to the write_init() callback, indicating that the SPI bitstream starts with LSB first. SPI controllers usually send data with MSB first. If an FPGA expects bitstream data as LSB first, the data must be reversed either by the SPI
