[U-Boot] [PATCH V2 3/6] spi: define SPI_XFER_ONCE

[Nikita Kiryanov]

The flag combination "SPI_XFER_BEGIN | SPI_XFER_END" is a common use
case of spi_xfer, and it can easily cause an already long line (spi_xfer
takes 5 parameters) to go over the 80 character limit.

define SPI_XFER_ONCE to be a shorter version of the above flag combination.

	DataImage SCF0403x LCD panel support". Split because it is unrelated to
	the patch it was originally in. (Igor Grinberg)
